Why does comparison even matter in terms of how many people saw it?
Why does your opinion of quality matter? Or mine?
Why shouldn't the opinions of millions and millions of other people matter as much or more?
The "popularity doesn't equal good" assertion generally only comes up when it's useful in ignoring the success of something one doesn't like. The idea that Trek fans in general, or the fans on this board, represent some exalted standard of taste as regards these things is arrant nonsense.
As far as I'm concerned, this movie was better than most Trek since TOS (the actual series) - and I've seen and liked most of those shows and movies.
