I didn't think an audio could pull off following up on Chimes of Midnight effectively, but Seasons of Fear is almost as entertaining and spooky, even if it isn't quite as polished.  There's a lot to like here, including the way the Doctor meets Grail out of order.  I don't love when we get to Nimon near the end, but everything else including jumping around time a bit in the beginning figuring out Grail, to that blockbuster of an ending where... something obliterates a couple of characters as a final little gut punch and hint at things to come, there's so much that Seasons of Fear has to offer.  It feels like a real adventure that makes good use of the Doctor and Charley.  I would definitely recommend this early run of Eighth Doctor stories.  They aren't all perfect, but there's a consistent thread of quality here that really feels like a polished and memorable equivalent to the best of the Doctor Who shows.  It is just so great this kind of content exists for the Eighth Doctor where it otherwise wouldn't.
