For me, the best episode was probably "There's No Place Like Home". It's like a movie! Also, one of my all-time favorites is "Enter 77". And I have a couple of worsts. "Flashes Before Your Eyes". It wasn't executed correctly. That being said, I liked "The Constant". "Homecoming", okay story, WRONG centric character, and "Everybody Hates Hugo"... just didn't like it.
