Just when we thought we were done with this subject, it rears it's head once more.
If Feig had said he hadn't tried hard enough then at least it would have been a humble admission. Even Joel Schummacher admitted he could have done a better job with 1997's Batman & Robin.
The actors are only as good as the director guiding them and if he's directing the best he can, then the movie will suffer and that is what occurred in this instance.
That and I've stated previously, the other reason that this tanked is because this franchise did not need a reboot. If the original had been terrible and the reboot would attempt to improve on it and make it superior then by all means have at it.
But it's like the idea of rebooting Back to the Future. You don't need to do that. Why remake/reboot a flick that is already a masterpiece? Simple. You don't.
Just because you can reboot a franchise - doesn't mean you should.
