Chocolate star, can I recommend both Battlestar Galactica (the remake with Eduard Olmos) and Alias (with Jennifer Garner)? Both far superior, IMO. Battlestar is one of the best series I have ever watched. (I used to work in TV and so am very picky ;) ). It's not pure sci-fi, it's about people, politics, relationships, etc. Utterly amazing.
Alias is also JJ Abrams and if you listen carefully there's an episode where they play Lost's Charlie's song!! It is quite repetitive but enjoyable in S1, then at the end it suddenly catapults into another dimension and becomes brilliant. And neither series leaves you with the bad taste in your mouth which Lost gave in droves.
