Only one movie this summer has me going bananas...Batman. I think Indy will be an entertaining film, but I get the feeling it will try to hard to be like the first one and fall short of capturing that magic again. I get the feeling this will be the old/wise/tough/still has his mojo but needs to retire movie. And like mafafu said, it'll setup the next trilogies with Shia. My two cents.
Bottom line, I won't see it opening day, but will try to catch it 2 weeks later.
