Worst film ever? Jesus, come on.
I thought Crystal Skull was a very fun film. I thought the last 30 minutes were too ridiculous and too disjointed, but the first hour is I think some of the best Indiana Jones stuff there is. The more I re-watch it the more I like. Again, poor ending and a disappointing last act, but overall a worthwhile addition to the series in my opinion. But then this is coming from a guy who holds Temple of Doom as his favourite.
