If I had to say something good about TFF, I would point out that they were at least trying to do a more "Trek-like" adventure. God-like beings, travel to the end of the universe, a more lighthearted tone, etc., seemed like an attempt to capture the tone of the show. It failed miserably, of course, with awful writing and directing, but at least they were trying. Way too many recent Trek films have fallen back on generic brooding villains, big space battles, etc. Makes for nice eye candy, not so good as a Star Trek film.
Which leads me to Nemesis. If I had to say something good about it...I would cut out my tongue, since there is nothing good to say. And this comes from someone who is a big Next Generation fan and can at least find something good to say about the other TNG films.
Both films are abject failures, but TFF at least tried something different, so that film wins.
