This is a very similar episode to the first one and is worth being binged right after it as it follows the previous attempt at reintroducing to a new audience what Doctor Who is and especially here, the "standard" formula of the Doctor's adventures as well as giving us more information on his backstory.

Overall I think I liked it less than the previous one. There was a lot of good and engaging ideas (I really like the gimmick of reusing Tainted Love and Toxic for comedy bits) and there was a lot of emotional writing about Doctor's backstory and him being the last Time Lord. But I think overall it was just a bit forgettable. Cassandra is not an engaging enough villain to carry a whole episode like that and while I respect a lot its attempt to blow your mind with crazy visuals and being over the top, I think it just ends up being a pretty standard, although pretty good Doctor Who story (and Eccleston is just that great of an actor as always).

I think I liked it less upon rewatching and it might just be more effective if it's your first time watching it.
