5 died cos they didnt have the budget for what they wanted to do, so what they were left with was shit. 10 was written by a big star trek fan, and I think that is the last thing you should ever do.
5 had some pretty awesome FX for it's day though.
I disagree on that, a fan would know more about the content...but it needed a clean up definitely.
Well see, what I feel is wrong with a fan writing a star trek movie is that they will try to include all the things that they think the fans have been wanting/asking for, and that just doesn't work. The wanting is a personal thing, experience if you will. A good movie will leave you wanting more, dreaming about it, thinking about how things could be or play out. If its all handed to you on a nice silver platter, you just feel empty at the end.
Plus they broke a fair bit of cannon as well, and that never goes down well with trekkies.
