I'm watching season 3 right now. I disliked Enterprise when it aired, but like it better now. Being closest to our time, it *feels* like a real ship, if you know what I mean.
I just saw "Anomaly" and loved the firefights, the attention to detail. The unconventionalness.
edit: Annnnnd "extinction" just wiped out all that good will. Ugh, that ending. And here i thought Archer wanted to keep the sample to use as a possible biological warfare agent.
