Sorry to say, but the finale was kind of a letdown, i know people are going to say stuff about this but we cant call a cat a dog.
The finale answered no questions whatsoever about the two timelines, the hydrogen bomb blowing up, or any decent answers, but brought all the characters together in a cheesy sort of way, it was weird to me atleast. Nonetheless, it was an epic episode, and a nice way to end the show, but I was kind of dissappointed, thats all.
All in all, a decent ending, killer camera work, nice dialogue, fairly good acting. I will watch it again, maybe to clear up some stuff, but I dont think that I can watch it again enough times to answer alot of the major questions.
