I didn't read all of the original City of the Gods script. I read up to the point where Indy was drunk after being fired, and that whole sequence was out of character for him. He got drunk in Raiders after Marion "died", but he never acted dumb. Though I guess it was no more out of character than the painfully-bad attempt at dry humor that was the sandpit sequence in Crystal Skull.
I'm one of those who didn't exactly hate the whole aliens angle. I get why Lucas wanted to do it. It was just executed poorly and the story had no tension. At all. And the first 30 minutes of it were really well-done (yes, even the fridge). So was the graveyard thing. I actually liked that. It all went downhill from there, though.
If they do a reboot, I think they should cast an "unknown." I think it needs to be an unknown so we can go prior to 1935. And I want to see him in China. Or India again (maybe the Nepal/Kashmir mountainous regions, trying to find Shangri-La). Maybe Japan. Or the incident with the Sultan of Madagascar.....
If Spielberg (or any other director) doesn't want to do "cartoon bad guy Nazis" again, then make the expansionist Japanese the bad guys if you set it in 1937 China. Or you can have an old Ford in a cameo role, remembering back to 1926 or something with his first adventures as a young "Dr. Jones."
Chris Pratt is the "it boy" now, just like Shia LeBeouf was back in 2007 when they cast him in Crystal Skull. I don't know if he'll still be the "it boy" after 2019. He's probably the front runner because he's already in a Disney franchise. If he is cast, I guess I'll just get used to it, even if I don't like him much.
It was a throwback to Raiders, before Indy was turned into a cartoon. The intrigue was there and had a bit of darkness to it. All of the banter between Marion, her new husband and Indy and the dynamics of that triangle was much more true to the characters as introduced in Raiders. I remember there was a great action sequence where what seemed like tiling and ceremonial decor turned out to be pieces of a giant circuit board or something, stone alien tech or whatever. Its been a few years since I've read it, but I remember being really impressed, and thinking THIS is the Indy movie I wanted to see. Until I read that script, I had been an ardent defender of the movie as is, but the previous version seemed so much better.
