Typical to the Indie films, this fourth one was filled with action, humor, and heroic moments you could cheer for. Overall, I was disappointed by how much CG (obviously) was relied on for action sequences (ie: Mutt flying on vines with monkeys? Come on - it was so obviously all CG and his character wouldn't have so easily picked up swinging like Tarzan). The alien solution seemed both an easy answer to the how/why question, and a far-fetched way to end it. Indiana Jones has always solved mythical theories, but he also made everything he did look plausible. Not this time.
