I've been really unimpressed with Heroes ever since they save the cheerleader and hence the world, but these last four episodes (to be specific) have been really really good. I suspect that it may be yet another awesome side effect of the writers strike. I read somewhere that the strike would cause the last few episodes of each series to be bad because the writers wouldn't have had as much time to revise and edit the episodes, but if the opposite is happening then that leads me to suggest that the Heroes script editing is actually causing the episodes to be worse than they were in previous drafts. Unintentionally of course.
Also Kristen Bell is awesome.
Now all I need is just_katarin to upload HD screencaps!
