I am going to have to wait until I see it. But so far all this is scaring me. Exact same thing happened with Revenge of the Sith and Kingdom of the Crystal Skull.

All my friends were shouting about how fantastic ROTS was, then I went and saw it and realized it sucked. Then it seemed like after I saw it, everyone started to admit how bad it was. I kept hearing that Indy IV was pretty good, then when I eventually saw it, I nearly puked multiple times. Now I can't find a person on the face of the earth who still admits to liking it.

My dad talked me into going to see it with him tomorrow (dah, same reason I ended up seeing ROTS against my better judgement), so looks like tomorrow evening I will be able to give a fair opinion.
