Yeah, its pretty bad...
It had some things going for it. It had a good look to it with the photography and art design, but you get that something is amiss pretty early in.
The story is very much rushed, clocking in at only 2 hrs. For a blend of two epic genres, and for a movie that's about 47 characters, this is way too short.
Making matters worse is Keanu whose acting has not improved and its hard to tell if he's just not bringing it or if there's nothing written in the character to bring.
Given the story, this was a big risk for Universal, but it's failures are not in the source material. Somewhere in are glimpses of a much better movie that could've been made instead. Its a movie clumsily made, so much so that the real merit is the money thrown in to salvage it and the special fx that it bought.
