Indy is really hard.for me to rank...the first 3 are so amazingly good and offer fans a lot to enjoy and have fun with. My pesonal favs fluctuated over the years with Last Crusade and Doom being my favs at different points in my life.
1 - Raiders (Personal grade - A+)
The original. I mean, come on, it's pretty much perfect. A true Hollywood classic like the original Star Wars. So many iconic scenes
and dialog in this one. Toht and Belloq are both great, evil villains with Belloq being Indy's dark rival competitor. Marion's an awesome heroine and was perfect for Indy.
2 - The Last Crusade (personal grade - A-)
This one is really good! The Nazis are back and we get to see young Indy for the first time! And of course Sir Sean Connery as Henry Jones Sr was perfection. The return of Sallah and Brody was also great! This one is great just like the first one. Julian Glover as Donovan is a slimy villain and really fun to watch. Elsa was a great new love interest for Indy, too. Too bad she just couldn't resist reaching for that grail!
3 - The Temple of Doom (personal grade - B+)
Severely underrated in my opinion. Yes, there are no Nazis but Indy would have been all over the world and that is why I really like Doom. We see Indy in a really dark story dealing with the supernatural and cults. Some people say Willie is hard to stomach, but that was the whole point of thst character. She was supposed to be annoying as hell. Which makes for some great comedic sequences in this one. And don't forget Indy's little sidekick, Short Round! The mine car and rope bridge sequences are also some of the best action scenes in the Indy movies, right up there with the desert chase in Raiders and Motorycle chase in Crusade. This one gets a bad rep. Plus, it is one of Williams' best film scores and definiely the best Indy score.
4 - The Kingdom of the Crystal Skull (personal grade - D+)
Definitely my least favorite and the least engaging of the 4. Some bad acting and awful dialog also ruins this one. I didn't have a problem with the aliens at all like some, though. Worst scene by far is the whole jungle sequence. Was fun to see Marion come back! Ray Winstone was also fun as Mac. If this one had been made around 1992, 1993 when Ford had done Patriot Games and The Fugitive it probably would have been really great. They waited too long. The CG also doesn't look good and it keeps it from feeling like it's part of the other 3. Also a shame Lucas scratched Darabont's script which was a lot better. Which also ended up forcing Connery to dropout in a smaller return role as Sr again. I thought Shia was okay as Mutt even though some despised that role. Overall this one falls flat. A lot of the jokes don't work or feel forced and Spalko was a weak villain and my least fav of all the Indy villains.
