I have to say any 4th movie in a movie series that comes out you have to take with a grain of salt, and can't expect too much from it. Remember Leathal Weapon IV? Superman IV? The Phantom Menace?

I think this will be on par with TOD & LC, as good sequels that are entertaining, and essentially not really needed, but a diehard will still enjoy it. The one thing I don't like is having Marion come back, as the great thing about each Indy movie is that he essentially had a different love interest each movie, a different sidekick, and that is what makes each one original in that respect. As much as I love her character from Raiders, and love Connery as Indy's dad, I don't want to see them in sequels after the fact, cause they give each movie their own identity.
