Pros and Cons

Pros
-Matt vs. Dad scene. Awesome acting.
-Matt "training" scene with Molly ("I love you" scene and Matt using it to evolve his powers)
-Mohinder + Nikki interaction. Mohinder actually makes Nikki a bit likeable.
-Hiro vs. Kensei scene. Very intense. (Save for the "power-up" Hiro recieves when Kensei threatens Yaeko)
-Peter meeting Adam
-Hiro and Yaeko farewell. Nice dialogues. ("As long as I have a voice, I will make sure that the boy Hiro Nakamura will have stories to help him sleep")
-Fast pace.

Cons
-Mohinder suddenly exposing himself. WTF. (I'm guessing this has something to do with the writer's strike? They are picking up the pace to be over as of December 3)
-Peter's trip to the future was...er...I felt short-changed. It's just like..."There's a virus. Go save the world." They didn't even explain what the virus does or show how it is transmitted.
-Nathan "talking" down Nikki. Mohinder didn't do jack s*** when he tried to talk Nikki out of messing s*** up, what's so special about Nathan? That one night stand they had back in season 1?
-CLAIRE! Jesus H. Christ....f***ing stupid idiot.
-WEST! First few episodes, he's like this snot in your nose you try to pick but can't get rid of (towards Claire), now he's all..."Oh I get it. I'm going too fast. If you want me to move away, I can do that." and the sudden "What is this? A trap? BACK OFF!" to Claire when he sees HRG when Claire basically trusted him with a lot of stuff.
