I remember feeling how... small the story from "Insurrection" felt compared to the epic stories of all the preceding movies, and how, on first viewing, "Nemesis" felt disappointing (though I have come to love it on re-runs). By this time, Paramount was pulling the plug - "Enterprise" was conscripted for 4-seasons (PERIOD!) so they could get it into syndication. The Trek factory was being shut down.
Whilst NEM isn't without it's flaws at least it was more abitious than INS.
