Enterprise was the best Star Trek series, imo. Ever other series was camp and tongue in cheek... watching Voyager (the same goes for TNG and DSN) again, I suddenly realise how naff the plots were. Enterprise managed to actually have realism (a first for Star Trek, :/) some of the time, and gave us more of an idea of how humans would fare if they suddenly found themselves stepping into a galaxy full of alien species.
I'll admit the later movies were much less camp than the series they led off from, but Enterprise IS the way forward for Star Trek, if you ask me. An Enterprise movie, I say.
