Well, just got back from seeing this one. I really liked it; didn't love it. If, like me, you go in just hoping it is a reasonably satisfactory send-off for the character and not terrible, I think it delivers on that. Sighs of relief all around.
I don't think it has the iconic action scenes or memorable lines to hang with the classic Indy trilogy, but in also lacks anything that ruins it as a movie for me, which Kingdom of the Crystal Skulls had in spades, and which frankly Temple of Doom is also rife with.
There are a handful of somewhat dodgy CGI shots, including some of the de-aged Indy ones, and I'm sure there's some people for whom once they spot the flaws in one de-aged shot they can't unsee them and the whole thing just becomes uncanny valley nightmare fuel, but it didn't bother me. The part that bothered me was more that they didn't seem to de-age his voice, and we all know what young Harrison Ford sounds like.
I'm sure we'll all get to hear lots of culture warriors denounce Phoebe Waller-Bridge's character, Helena Shaw, across the internets. There is one "I'm an independent woman" mini-speech that was in at least one of the trailers (and maybe shoehorned in for the trailer) which is a bit unfortunate, as it just reads like her studio-approved character notes being rattled off, and her bragging about her "self-sufficiency" is really obnoxious under the particular circumstances which I won't spoil. But she was mostly a pretty cool character for the most part, and if they want to give her and her kid sidekick a Disney+ series I'll probably watch it. She does pull more focus from the titular hero than any of his various side-kicks have before, and maybe that is part of some sort of spin-off plan, but I think it has more to do with the limitations of elderly Indy as protagonist is an action oriented series.
The action scenes were a little limited but what the elderly version of even a hero as pulp action as Indy can semi-plausibly do, and while they made it work through the beginning with de-aging and the middle with vehicle (and horse) chases, they just seemed to have run out of ideas of how to do action scenes with him in the final act. There is a big and very Indiana Jones-y stunt near the end that pointedly goes to Helena rescuing him rather than the other way around, and while I'm sure we'll all hear plenty of rants about how this relates to Hollyweird's woke feminist agenda if we visit the fora where such rants happen, I think it speaks more to the actual limitation on the movie that this 60-something character (with enough mileage to be credibly played by an 80 year old) just has limited action hero potential.
Edit: Just after I finished typing this, I saw a link to a USA Today article that boldly ranked the Indy movies with this one above Temple of Doom at number 3. (their rankings, which you can probably predict from that, were 5. Crystal Skull, 4. Temple of Doom, 3. Dial of Destiny, 2. Last Crusade, and 1. Raiders). I would say I agree with that assessment on overall quality, but that it fails to acknowledge that in the mess that is Temple of Doom there are some of the most iconic parts of the franchise and I just don't think Dial of Destiny really stands up to that.
