re: Batman vs superman. Worth a watch or don't bother?

I guess the objective question is this: do you want to see a movie with Superman, Batman and Wonder Woman in it? Do you want to see these characters (the actual title characters) in any movies anytime soon? Would you like to see a Justice League movie with a huge budget and top-notch effects?

If your answer is yes, then you should watch this movie. This made over $800 million dollars, it is not going to be rebooted. If the franchise craters, there's a very good chance it will be shelved, and not rebooted for probably at least a decade. You have to figure for an audience cool-off time, development, and then actual filming again... at which point we might all be done with the superhero genre, and it wouldn't be worth the risk to make. They very likely might decide to just keep it on the CW, safe and cheap, and string the soap opera stories along there. We would never get impressive visuals like we do on the big screen (and even the haters admit this movie delivers on that account).

None of these comic book characters are ever going to be exactly the way we imagine them to be.
