Agree fully. And this is probably why I've felt - well, here 'pleasantly surprised' sums it up well. My expectations were in inverse proportion to the hype...but while the film is self-important, derivative and silly, it is also earnest, likeable, spectacular, beautiful and kind of goodnatured. So I'm giving it a pass. I'm almost liking it more with time passing, in fact. I'll see it again at least a couple of times.
I suspect you'll really, really hate it, and you probably would even if it hadn't been hyped at all. The story points, questionable physics and biology, the plot holes, the hackneyed characters, you could really have a field day with all that.
