Where Crystal Skull was cartoonish to the point of stupidity, this is bland to the point of soulessness. There's no flair, no wit, no excitement, no sparkle.
Even ignoring the CG deaging which is often betrayed either by a lifeless digital gloss, or the more restrained acting style and drooping face of modern day Ford, the prologue is uninvolving, shot with a murky day for night look and missing the point of an Indy prologue - to start at a breakneck pace with something different to the rest of the movie and even the past movies. This is an anonymous Nazi chase full of CG figures jumping over train cars. It's Indy's Greatest Hits, made by people who seemingly have never actually seen the other movies. As with the entire movie, it lacks that Spielbergian verve that even Crystal Skull showed at points, and doesn't show any of Mangold's strengths either - the framing is careless, the action muddy and the cinematography flat.
The script is begging for a Tom Stoppard rewrite, to trim it down and maybe put some actual jokes and characterisation in there. Teddy is a charmless Short Round knock-off, Waller-Bridge gives it her all with Helena but has nothing to work with, and Indy himself has been given the Force Awakens makeover - he's now a failed husband and father who doesn't have the will to live anymore (pretty funny that they gave Mutt a nasty pointless offscreen death via 'Nam, though). Sallah and Marion are wheeled on and off stage for some quick fan service (along with some other clumsy box-ticking like a ten-second sequence of bugs crawling over the heroes, or Indy throwing out a Kali mention for no good reason), and the villains barely exist. The action sequences mostly involve Indy driving a CG vehicle because that's all he can do now. It's too goddamn long at over two and a half hours, 26 minutes more than the now second-longest of the franchise, Last Crusade (which could have done with chopping out that Alexei Sayle scene and being a couple of minutes shorter itself). And, somehow, even the big finale of Indy traveling back in time is carried out with as little energy as possible and tanks the entire movie.
Crystal Skull may have been awful, but at least it was an awful Indiana Jones movie. This is just some charmless 2020s schedule-filler wearing an Indy mask.
Rating: if not terrible then terribly bland.
