OK, I absolutely LOVE Heroes, so i am still buying this season, and would still recommend it to anyone else. my only problem is that with the writers strike the show really struggled when it came back. the writing wasn't as fresh, the stories sort of struggled, and as a whole it just didn't draw you in nearly as well as the frist season did. still, though it was entertaining and a joy to watch. i think season 2 was more just a victim of circumstance and bad timing. you can look at just about any show that came back from the strike, and they all sort of struggled. it was tough for the writers to really get back into the flow of the show right away, and with the NBC execs and the producers pushing them to crank out episodes so they can be back in the game right away, it caused a bit of a slump.
i'm a little curious as to how there are so many episodes on these discs, when the season 2 was pretty short. are they going to include the NBC.com Webisodes or some of the original Villians shorts?
All-in-all, you can complain all you want about how season 2 wasn't that good, but if you enjoy the show as a whole and want to get caught up before season 3 kicks in, i highly suggest picking this up. also Kristen Bell is in season 2, and boy is she fun to watch!
