With a heavy heart, I think I have to concede that Indiana Jones and the Dial of Destiny is not good. It's probably even bad, because even the parts that are sort of entertaining ultimately disappoint.
Take for example the prologue with a de-aged Harrison Ford. The technology used to do it is impressive, and only looked awkward in a couple of shots for me. It's Indy adventuring during the end of World War II, and it almost captures the adventure/action you'd want. However, it's so dimly lit that barely anything can be seen. It's probably to disguise the de-aging, but it's disappointing. The stuff you can see isn't particularly great, but it fares better than the next couple of big action scenes.
These are spaced out over the next 80 to 90 minutes. Said 80 to 90-minute stretch is honestly very boring. Harrison Ford is trying, and John Williams' score is pretty good. I usually like Phoebe Waller-Bridge, but her character didn't work for me. Barely any of the humor landed. The action is incredibly dull and quite often poorly shot. Ford himself isn't in much of the action, which is understandable, but it also begs the question of why they even bothered trying to make an action movie with an 80-year-old man.
I swear characters enter a hotel at night, and they come out the front door five minutes later and it's the middle of the day. Why did they bring John Rhys-Davies back without giving him anything to do? Why was Antonio Banderas in this for like, five minutes? Why do they think audiences will care that Banderas and Toby Jones play "friends" of Indiana Jones, even if they've never been seen or mentioned before this film? Why does Hollywood keep wasting Mads Mikkelsen?
The final half-hour is sort of fun, but it concludes very abruptly and awkwardly. Some people will hate where the movie goes regardless, but I thought it came close to giving the whole thing a pulse. The final scene itself sounds like it should work on paper, but it did nothing for me emotionally. As I walked home, I liked the movie less and less, the more I thought about it.
It's so lifeless and uninspired, and even if maybe a third of it is passable, the rest is a combination of boring and baffling. Even if you're a big fan of the series, I wouldn't bother. This is a good deal worse than the other four.
