I agree with that assessment. I found it pretty engaging the first time around, loads of moments where you're going "that's lame" or "that makes no sense", but a fair bit of action, humour and colour.
The closing sequence was crap and bloated, the film was overlong, the characters are wooden and tedious, all the usual criticisms but then this isn't really a "drama" at all ... it's something else. Explody rainbow froth.
The thing that gets me, though, is that with a bit more effort on their scripts, which must be a tiny, tiny fraction of the overall production cost, some of these films could actually stand on their own two feet as dramas and still include all the frothy elements.
