Oh yeah, I pretty much agree with going downhill every season too. I've said that before.
I just honestly don't find Heroes that good. I wish I did. So many people seem to eat it up.
And like I said, it's hard for me to admit that something I've loved for a while just downright sucks. I've only done it with something like The Simpsons and Family Guy.
Example: I will watch Live Free or Die Hard opening weekend and I will probably eat it up, even though it looks like shit.
