I knew Indiana Jones 4 might be a problem when they mentioned the Nazca lines and I started twitching violently in my seat. Kevin put his arm around my shoulder and said "There, there. It's okay. It's just a movie." I retain just enough of my South American archaeology chops to get twitchy.
It wasn't a good movie. I'd say it was about half a good movie. The other half was mostly "We have CGI! And George Lucas still can't write!"
Still, it's Harrison Ford, and I'll watch him read the phonebook if he's got a bullwhip in his hand.
