So. . .I was actually very disappointed with this episode, especially after last week's episode. I was expecting some interesting developments, but it really failed to deliver.
I liked that they explained how Peter lost his memory and why the Company is tracking him, I liked Elle and Bob, and I liked DL being a hero, but everything else felt weak. I didn't really like that Adam's blood saved Nathan. That felt contrived. I also though DL died like a punk. He deserved a WAY better death than that. And ,of course, boring twins are boring. Also. . .I'm not really sure I like them setting up Adam as ambiguous as far as his allegiance goes. Is he good? Or is he evil? How CAN he be good? He's Hiro's villain, and the Company felt he was too dangerous.
They completely left out what happened with Matt and his wife (Yes, we know, but still), how he hooked up with Mohinder and Molly, how Sylar wound up where he was, and how Noah and Mohinder decided to conspire against the Comapny. There was needless exposition with both Peter and Adam's storyline and Nikki and DL's storyline and the episode suffered for it. I also felt that the last scene with the boring twins was completely unnecessary.
OH, and we STILL don't know what Mama Petrelli's powers are. I'm going to assume it's Persuasion, but it's getting kind of ridiculous.
