The Alternative Factor
I used to have an utter distaste for this episode. I thought it was nonsensical and pretty boring. I mean you had an alternate universe story, and this is the best they could come up with? Well, I watched this episode tonight and to be honest, I still think it's a weak episode but it was a lot more interesting than I thought before. Maybe it was Kirk and Spock's discussion about matter and anti-matter, or Kirk's going into the alternate universe and talking with sane Lazerus, who I wished played a bigger role. It's still a little boring but I don't utterly hate it as I did before. It is still worse than a lot of the 3rd season episodes, like Spocks Brain, though.
City on the Edge of Forever
I find this episode a little overrated, but watching it again, maybe not as overrated as Trouble with Tribbles. This is your classic love story and Edith Keeler reminded me of Julie Andrews playing Marry Poppins (A movie I watched over the Holidays for the first time in years). That last scene is still one of the most dramatic and probably the most iconic scene in the franchise though, but the reason I think this episode is overrated is because I don't gravitate towards romance stories like a lot of people do. It is great to see Kirk and Spock in present day clothing though. Always love wihen characters are out of the uniform.
