Wow... finally watched the finale.... I must say it left me sad, but satisfied.
I do feel that the writers jumped around quite a bit in the last few seasons though. The show had more of a realistic feel to it in the earlier seasons, then jumped to William Bell creating genetically mutated creatures and trying to create his own universe and destroy ours int eh process while using Olivia as the catalyst, then the next season deals with the alternate universe and then the machine, then Peter being erased from existence, then they just conveniently bring him back with no real solid explanation, we are just supposed to accept that he's back because he had such an indelible footprint in the hearts/minds of others?! Then now all of a sudden we flash forward 21 years into the future and it's this whole Observers Invasion storyline???! Then on top of that we miss the whole Peter/Olivia romance and getting married, and her getting pregnant and having a child stuff?! WTF?! --
