Meh- not bad, but nothing extraordinary either. This new instalment could have been awsome. Instead you get the same old, tired formula. A lot of unnecessary fight scenes (the one between the sisters who first try to stab each other, then one says "peace " and all is forgotten).
The villain is basically a Bond villain copy, not very menacing. The action and CGI are good and there are a few funny scenes.
Both Scarlet and Florence are great actresses, unfortunately they don't have a lot to work with.
All in all, you get what you paid for, a no brainer popcorn flick, nothing more, nothing less.
