I dunno, I don't think it was THAT weak, it was right in line with the whole "love will save the world" thing that Shaft was telling Peter Petrelli. Yeah, a Matrix-like battle would've been cool, but we've all seen that before... (and that ending sucked worse anyway!)
My questions are this...
1) Yeah, WTF with Sylar? Who did he kill to get the ability to survive that hit? Or maybe someone just shoved him down the sewer... who knows. Instead of stuggling to move the manhole cover, he could've melted it.. much easier, right? So, what gives? I think someone moved him. It's not like Linderman healed him, his death scene more than made up for the "so-so" ending!!!
2) What's with Peter and Nathan's mom? What's her power? Is she the "worse than the boogeyman" person??? She's got something... can't figure that one out. Oh well.
