Nemesis isn't the best Trek film and it isn't the worst. I actually rank it as the best of the Next Gen films.
Same here. As a matter of fact it is the only Next Gen movie DVD that I own and re-watch fairly often.
Great points for me are:
Riker and Troi's wedding.
Riker finally becoming a Captain.
The fight with the Reman boarding party and Riker's fight with the Viceroy.
And Nemesis led to my favorite lit series ever; Titan.
