While my opinion of TOD as a whole leaves something to be desired the opening scenes are a banger and the climax delivers with Mola Ram's demise and the children being freed and returning to the village. It's the most effective use of the Indy theme outside of
Raiders itself.
Admittedly I haven't seen it in a while, but ToD was always my second favourite after Raiders. I like the darker tone, I like that they tried to do something different and I loved Short Round. In hindsight I appreciate there's some problematic elements there, and a definite white saviour aspect, but on the other hand we get PoC who have agency and who are the bad guys, not just hired thugs, and the idea of a western archaeologist returning a sacred object to the local population rather than stuffing it in a museum is incredibly ahead of its time (on screen at least.) I even don't mind Willie.
Last Crusade on the other hand, as others have noted, just felt too safe and familiar. Much like Jedi it's a case of "remember all those things people loved from the first one? Let's do that again." so we get deserts and Nazis and Christian iconography.
I like the banter between Ford and Connery and it isn't like I hate it, but many of the set pieces always felt very staged and some of the effects are ropey. Don't get me started on that whole opening segment where ever aspect of Indy's look and personality is formed in the space of five minutes, that didn't set me up to enjoy the rest of the film.
I've only seen Crystal Skull once, but I don't recall hating it and at least it tried to do something a little different again. I still recall the nonsense online about how preposterous the notion of Indy meeting aliens was. Wrath of God, magical stones and cups that can confer immortality are fine it seems, but UFOs? Ridiculous!
This trailer did get me excited though and I might commit to a re-watch of the others before five comes out, see if my views have shifted any.
