To me, this movie looks okay. Probably not spectacularly bad or anything. I'm certainly not rushing out to see it though.
It seems a bit crazy to me to risk putting so much money into a movie that isn't more or less guaranteed to make it back. Shit like Spiderman or Lord of the Rings or the latest animated movie the kids are gonna flock to in the holidays, okay, you can spend as much as you like and know you've got a safe audience that is gonna come and see it. Spending 250-300 mil on something like this though seems like it's asking for trouble.
