God, it was awful. One-dimensional characters with stupid names and embarrassing dialogue. Deep, deep in the squalid bowels of the plot, there was a story idea that Wasn't That Bad. Unfortunately, not only is it swamped by everything else, it's also just a set-up for a sequel.
Strangely, the film didn't even seem finished - there were loads of scenes where the CGI looked like it was a test shot, not the fully rendered finished item. Bizarre.
Unsurprisingly, there's lots of strange, unnecessary specialised craft which are presumably merchandising.
