Exactly. FC was just on TV this weekend (on AMC, I think), and I intentionally watched it looking for inconsistencies, nit-picks, an plot holes. Believe me, there were plenty.I did like them a lot. They are the best Star Trek movies without a doubt, but by inconsistency standards, they don't work. Neither do the rest of them. That's why I don't pay too much attention to inconsistencies.
If I were a person who watched FC for the first time, and dutifully made my nit-pick list, I would have probably hated the movie. Luckily, I've seen FC enough without trying to nit-pick it and I find it to be a very enjoyable film.
