I love this show. That being said, it has some flaws. You can tell when it went downhill is when J.J. Abrams stopped working on it regularly. Season 1 is great, Season 2 is great, Season 3 was OK, Season 4 not so great, and I'm going to pretend Season 5 didn't happen. I'd have to agree with some of other reviewers on here, it seems like they ended up with a bunch of different writers that lost direction or understanding of what the show was about and where it was supposed to be going. It started out as a spy show with a hint of sci-fi, and ended up the other way around which was just weird. It seems like the only person who really understood the whole Rambaldi thing was JJ. I think that the actors did a good job with what they were given. Watch Season 1-3 if you want to check it out. Its on Netflix as of 8/16.
