I've spent the last three days watching Heroes Season 2.
Here's my review:
Season 2 is far from what Season 1 have accomplished. I expected more from the show, more substance, different plot but it failed to deliver that. In this season there's nothing to fight for, something substantial. Season 1 and season 2 have the same plot - saving the world (again!). It would be wonderful if they think of another storyline and not by just saving the world. BORING!
Mohinder is an idiot. And also Peter. They really can't do anything important.
But I love Peter. Yummm! LOLZ
