Not bad... just flat.
I went in with insanely low expectations and would say it's on par with those lite Marvel movies like Daredevil and Ghost Rider. Extremely mediocre but enjoyable enough if there is nothing else on. Taylor-Johnson gives it his all and some of the action scenes are good (especially a chase through London).
This is nothing like the comic character except for the name and the Russian background. The story is crap, the dialogue even worse, too many characters that didn't need to be there... No way this needed to be well over 2 hours long.
