Being in the UK, Season 4 hasn't started airing over here yet. However, my view of Seasons 1-3 is that they undermined everying that had been established by the other 4 series before it, such as First contact with the Klingons (Chronology gives it as 2210?), Suliban and Xindi (If they are that important, howcome we never see them in any of the other series?), the ship itself (uh, Akira?), to name but a few... Unless season 4 is a drastic improvement, I think I'll be glad to see the back of Enterprise.
