I don't think you (or most people) would like it seeing it for the first time now. I saw it in the theatre and loved it, then was flabbergasted when I went online and saw what a pounding it was taking from the fanboys. "What the hell do these people want?", I thought. It was only later that I realized the real reason I liked it so much was because I was totally blinded by my own hype. When "Generations" came out, I wasn't really aware enough of movie releases or a frequent enough moviegoer to see them, and when "First Contact" came out, I just didn't have anyone to go with or time to see it. When "Insurrection" came out, I was too busy attending a new high school outside of North America to be aware of what was going on with movie releases there.
"Nemesis" was the first Star Trek movie I had a chance to see with someone since becoming a Star Trek fan circa 1992, so I was incredibly stoked about seeing it. After ten years of fandom, I finally got a chance to go to a theatre and see a Star Trek movie as a full-fledged Trekkie, old enough to appreciate and feel grateful for the experience.
With that kind of bias, they could have thrown together just about anything with the TNG crew and I would have eaten it up happily, and that's basically what happened. I watched it and was just enthralled the whole time with the thrill of seeing Picard, Data, and all my favourites up on the big screen for the first time. I even enjoyed the very obviously cartoonish villainy of the bad guy, not realizing what a stupid idea the character and plot surrounding it were.
It was only later when I gave some serious thought to the plot and characters I'd seen that I realized what a poorly conceived movie it was. So I think if you can go into the movie under the warm glow of unshakably positive fandom-inspired enthusiasm and do the proverbial "turn your brain off", you can probably enjoy it.
On the other hand, if you approach the movie with an alert mind that's going to try to thoughtfully assess the plausibility and creativity of what you're seeing, it'll probably be a huge drag. When it comes on TV now, I can barely get through 5 minutes before I'm so bummed out by its mediocrity that I have to change the channel, but seeing it for the first time, I was in awe from start to finish. I even bought the climax as a powerful and poignant moment rather than the cheap shock tactic it really was.
