Anyway, I've been watching the repeats of series 4. I think the show is beginning to get tired, with the zenith being back in series 4. That being said, there were three good episodes that I've seen so far.
The Zazzy Substitution: Sheldon breaking up with Amy and buying up cats. What is there not to like?
The Hot Troll Deviation: The return of Katee Sackhoff and the premiere of the hilarious George Takei. 'Nuff said.
The 21-Second Excitation: The return of Wil Wheaton, Amy and Bernadette making Penny uncomfortable at a slumber party, the best episode of the season so far.
The Doctor: There's one thing you never put in a trap, if you're smart, if you value your continued existence, if you have any plans about seeing tomorrow, there's one thing you never, ever put in a trap... Me.
