Seriously? TSFS is probably my second favorite TOS movie behind TWOK. I get the criticism of the fairly one-dimensional villains and fake Genesis planet, but the movie still has such an incredible
atmosphere and sense of romance about it. The story is simple but compelling, it's got a ton of fun character moments, and it's got freakin Christopher LLoyd as a Klingon.
I seriously don't understand why fans have such a problem with it.
