Just take it as it is and it is very good. The special effects are excellent and action is non-stopped. There are plenty of jaw-dropping moments in this movie.
Chances are that most of the stunts are highly unlikely, but you're watching a movie, purpose to entertain. It's like watching a superhero movie, no spiders don't make men that shoot webs, or rage that turns someone into a superhuman green giant, but they do entertain.
I was very entertained. If you like action, check this movie out and you will not be disappointed.
