Yeah, the pacing was bad. It got too exposition-heavy and wasted John Hurt in a tiresome role. And I didn't like the way Marion found extreme peril such a laughing matter, especially considering it involved her son. Couldn't she have screamed like Willie?The Ancient Alien stuff has been around for decades. Got real popular in the 70s for awhile, died down then came back with the History Channel show.
For me, KoTC problem wasn't the alien part of it, it was the bad writing. Fun idea to explore, poorly executed.
Honestly I should probably forgive it that last point. Its true failing was that it was an action-adventure movie that was kinda boring for long stretches.
