Yes, it was. Apparently there was much hoo-ha amongst the production staff about filming it until William Shatner turned round and said "for god's sake, let's just film it!"
I'm a long term Trek fan and TNG is by far my favourite series, but no, Nemesis was awful. Not better in any way. Not better than anything. Bad, bad film.
In fact, I remember Jonathan Frakes being asked if he wished they'd made another film, a couple of years after Nemesis. He responded with the following (paraphrased, as best as I can remember it);
"Yes, I wish we had made another film after Nemesis. In fact, I wish we'd made another film instead of Nemesis."
Even the cast hated it!
