Attention Hollywood
You've spent all this money on so many of these but have you examined why they fail?
A) The pretty male lead who keeps winning by accident. You show us all these incredibly powerful foes, and after a short comedic training, the hero pretty much seems to have Longshot's powers from Marvel Comics. You can't beat dumb luck!
Girls don't go to see these anyway, so why use a pretty guy to try and attract them?
Gyms are full of more believable guys, and really you never get a great thespian actor anyway, so why not save some money and get a guy who looks tough, instead of pretty?
B) Too much CGI not enough story. It's like every villain can morph into a dragon, or a giant, and fights a long battle scene against a hopelessly outmatched hero, but they never lose.
C) The person who trains them. Usually the last of his kind or the best, but flawed, not much faith in his trainee and a 15 minute(if that) refresher course in being a Jedi master, a 7th son, Ghost police officer or Men In Black and we're off fighting villains way, way, way out of their league
D) At least Men In Black had a good actor in the lead, who had a good personality, could crack HIS OWN JOKES, instead of just hammy Tommy Lee Jones doing it. They explained he had hyper reflexes and was armed with a good weapon and was pretty tough. That's why it succeeded, the last 50 clones haven't.
