Onto the final episode of the Tom Baker era. It’s been a long old road, with its highs and it’s lows but I’ve thoroughly enjoyed it overall and there are many classics I’m excited to watch in the future, but first we have to go through what must be the biggest finale of the Classic Era.

It's the end, but the moment has been prepared for. This episode is the most doctory the Doctor has been - the Watcher told him from part 2 that he's going to die, but he doesn't give up, is relentlessly thwarting the Master at every turn, but he keeps coming back with more. He's rather short with Adric in this story, but there's still a few hints at comedy, but the Doctor that we once knew is gone, because he has to prepare for the worst. That final confrontation with the Master always has me on the edge of my seat every time I watch it, but this time even more so as all his past friends and foes show up, and now that I've watched every single one, makes me tear up a little as we remember the past 7 years. I also love the way he interacts with Tegan - part of me wishes she was introduced earlier in the season so we could've seen more of them spending time together. Speaking of Tegan, she's been in one episode and I already love her - I think she's my favourite companion since Sarah Jane. She's strong, independent, hilarious, and not afraid to speak her mind - the way she takes on the Master having barely known him, and the heartbreak she experiences when she realises her aunt is dead is so brilliantly performed, she just runs off into the corner and bursts into tears - and she's Australian. I'm not from Australia, but Australian companions are always good. I love how she just runs around the TARDIS for a few hours, then yells at the Doctor, and he and Adric are just left speechless. One of my favourite lines of the story come from her - “Adric and Nyssa went to look for the Master!“ she says whilst grinning like an idiot. She's so out of place and I love it. Nyssa just shows up and I don't know why, but Adric clearly has a massive crush on her. She goes through a lot in this story - first, she loses her father, then her entire planet. She must hate the Master. Adric gets the spotlight as companions for episodes 1 and 2, but then is sidelined with Nyssa to allow for Tegan to become the main companion. However, all three make for an interesting dynamic, but it's a shame that intimate teacher-student relationship is gone and he ended up being like their space dad. But all of them are still fantastic - especially Tom Baker, who was a fantastic Doctor right to the very end!

It's fantastic how this feels like a New Who series finale, drawing on so many elements over the previous stories. Remember Romana? The Doctor gets some closure from her leaving and moves on, jettisoning her room as she'll never use it again! The Master returns? That story thread is followed up upon in the very next story! Remember Traken? Entropy has destroyed it - that particularly highlighting the epic scale of this adventure; nowhere is safe! Remember the E-Space trilogy? The CVE is the key to it all! I found it very funny that they were able to find CVEs so easily in N-Space, which is infinitely bigger than E-Space, where the Doctor, Romana, K-9 and Adric spent months looking for one. I liked the Ainley Master, but he felt a bit cheesy, considering he didn't show up until like halfway through part 3 and only was around in the first half via laughter. However that's not a fault of the performance. I liked the way the Doctor couldn't trust the Master once they teamed up in the final act, but there was still an underlying level of brotherly respect between the two - it's good that they maintained that. His TARDIS was very bizarre though - it seemed that his chameleon circuit wasn't fully functioning either! It seemed to only change shape when it was about to take off!

I'm a little disappointed I don't have the Season 18 Collection Boxset, because I would've loved to have seen the special effects for this story, cos I think they add so much more to the story. Despite this, it still looks fantastic - we see more of the TARDIS, and the Cloister Bell rings for the first time, and here it's a lot more ominous and scary than it is in the future; Logopolis is beautiful, the set design is just amazing and I've said it before, and I'll say it again - Season 18 has done marvellously in showing off these purely alien worlds. The direction and visuals of the final confrontation on Jodrell Bank is brilliant - it just looks excellent, but it looks so much better on the Collection Boxset.

Auntie Vanessa's choice of weapon is: a flat tire. Gotta love her. It's a shame she was killed off so early - her and Tegan had some really strong dialogue, and I would've loved to see more of her in future stories. Is it me, or does the Monitor look a lot like Noel Edmonds? The themes of worker exploitation amongst the Logopolitans is very interesting, and only Tegan would pick up it, being a feminist, everyday woman. It's a shame it's being overshadowed by all of the other stuff though.

The music is so beautiful, there's a sense of doom and grimminess that accompanies this story, but at the same time suggesting a drastic change to the show, which there will be of course.

What a marvellous end to the Fourth Doctor. There's a reason he's the most iconic Doctor of the show - he's not my favourite, but god does he have good stories! The Hinchcliffe Era is peak Doctor Who, with The Talons of Weng-Chiang being an amazing finale to the end of the golden era. Then we've got an SJA-esque show - again, it's not the best but there are some whoppers of ideas - two Time Lords as leads, the first series arc, a robot dog, even the great Douglas Adams gets involved! Then a return to form with the gothic/science based season 18 to kick off the massive JNT era. This time on the show is so influential. And it's amazing, I love it so much. While I'm excited to see what the Fifth Doctor has in store, I'll never forget the fun I had with this Doctor. And what a story to end on, eh?
