My complaint with it wasn't as short-pointed as "nuke the fridge" or "aliens." My problem was that the characters were not developed to any degree. At what point was I supposed to care about Ray Winstone's character? That part where he kept saying "Jonesy!" with the bright light on him. What was up with that? You could tell where Lucas had control, because those were the sequences with over-the-top digital effects being used for their own indulgence. I can understand effects, but only when they look real and believable. Giant green screen effects were the emphasis of the Star Wars prequels, and the stories suffered for it.
It's like Michael Bay, only more colorful. I don't know what else they could have used for the quest objective, but the point is not the object itself. It's the journey and how the characters interact on the way. Even though it was in the title, Raiders of the Lost Ark was about how Jones interacts with his former love interest and plays against his rival. Temple of Doom was about enduring the possible annoyances of an overbearing and demanding companion as well as a youngster. Last Crusade was undoubtedly about Indiana's relationship with his father and where he came from. The supporting characters were engaging, entertaining, and interesting. Does anyone even remember the name of ONE supporting character or villain from Crystal Skull? What were they there for? The character is, for all intents and purposes, figuratively killed off. They could not do another movie, and the rumors of continuing with Shia LeBouf in the lead had better remain as rumors. I will not waste my time or money for that.
