As the original perpetrator of this thread, I have to say that my intent was indeed for it to be humorous for those who liked the movie as for those who did not.
Every movie has its plot holes or errors (especially in science-fiction - but then again, sometimes I wonder if life itself does not have its own plot holes as well), and I agree with Tobian that the difference is that for some movies we can overlook them or explain them away, for others we can't, won't, or don't want to. This allows to nitpick as much as we want, and, if it's not overly laced with vitriol, we can all laugh about it.
Just a couple other ones that came to my mind while writing this:
- Starfleet does not mind if its stations or ships carry little creatures of dubious purpose or intelligence, as long as they appear to have a liking to one of the crewmembers.
- 23rd century cops drive futuristic overbikes, but they are unable to overtake a vintage wheeled car before it drops into a canyon.
