Reviews don't mean nearly as much as people want to believe they do. What is going to cause this movie to sink or rise is its Box Office performance.
I also firmly believe that it's ludicrous to act like Constantin and FOX are just going to give the rights back to Marvel if this movie doesn't do well at the BO. What is more likely to happen is that the distribution rights will stay with FOX and they'll turn to their golden boy Bryan Singer to make the sequel since he's proven he knows how to save a franchise.
