I watched the first 2 episodes, and have come to the firm conclusion that Heroes has officially jumped the shark. Most people I know that watched Heroes liked it, but it got a little more convoluted towards the end of season 2. Now, with the new season it gets even more convoluted, and the characters they tried so hard to build up are now turning on a dime.
SPOILER IF YOU HAVEN"T SEEN THE FIRST 2 EPISODES---------
How is it possible that Mohinder, who has been nothing but a concience as well as a narrator for the show, all of a sudden makes a rash, ridiculous decision that has more impact on him and the world he so cares for than anything he could have before. How do they take a deliberate scientist who had done nothing without thinking things through make such a huge choice, on a whim?
How many kids are they going to have in the Patrelli family? Before we know it, Hiro will be a love child who is Nathan and Peters brother too...So stupid. That is exactly when the jump took place. It's too bad, because it had a lot of promise...And now we get something retarded. Sad stuff.
