Okay, now that I've read through this thread, all I can say is -- Gruff is RIGHT on the money, and as eloquent as any critic. More so than the vast majority of the ones featured on Rotten Tomatoes. Also more insightful.
So it's good to have you here, Gruff!
Irish -- this is much, much better than TLC. For the reasons I outlined above, and also because this is the first Indy movie since
Raiders that's not an exercise in genre for genre's sake (and I'm saying this as an unabashed ToD fan). It actually takes place in a real world, with real people populating it, with no sneering, mustache-twirling villains, or two-dimensional heroes.
I was also quite amazed at how vast that world felt. You know how sequels tend to develop their inner self-referentiality to the point where a fourth installment can hardly ever be more than a rehash of what had gone before? Yeah, none of that here. You get to learn more about what Indy did in the intervening years (and hear him talk about one of his Young Indy adventures!), and you get more glimpses into the secret history of archeology and science than you can shake a stick at.
And Lucas weaves the many disparate bits of the Crystal Skull lore into an amazing tapestry. But more than anything, I was impressed by how well Koepp has written the entire thing. When he said he didn't write a fan script, he really meant it -- and the fans should be very grateful to him for that. His plotting is more organic than Jeffrey Boam's, and he never resorts to having his characters speak in quips and one-liners, the bane of modern blockbuster writing.
Can't WAIT to see it again. Hopefully it will come to the local digital cinema, though -- it was done in full DI via eFilm, and the 35mm print we saw of it was grainy, overcontrasty, and out of focus. It's mostly the fault of our own projectionists, but digital screenings take most of their errors out of the equation. Well, if anything, it'll look brilliant on Blu-ray later on.
And the art direction is so good, and the level of detail in the money shots so stupenduous, you really owe it to yourself to see it in highest quality possible.
