Two big-budget sequels to sci-fi icons, Blade Runner: 2049 and Alien:Covenant, had stunning visuals, especially Blade Runner, but both left me cold. They are unremittingly grim.
Blade Runner: 2049 is a masterfully crafted film. Cinematography is unparalleled. But plot-wise, it treads well-worn ground. Once again we are in the future where everything is awful except for a wealthy elite. I am so deeply weary of dystopian visions. Even more so of dystopias that are kept in place by a corrupt and ruthless elite. Honestly, it's like sci-fi filmmakers can picture no possible futures for the world except to become North Korea writ large.
The plot revisits the themes of what it means to be human, what is the value of non-human life, or almost human life, etc. Essentially a more elegant take of various Star Trek episode themes. Yawn. But it is truly a feast for the eyes, and it's always good to see Harrison Ford in the old roles, which he still carries off like a true pro.
Alien: Covenant is less high-minded and less extreme in it's visual mastery, but still striking. Technically, it is both a sequel (to Prometheus) and a prequel (to the original Alien). It, too, trods well-worn ground. Two robots, one has turned against humanity, symbolize the discourse on whether humans are good or evil. Of course, all this was set in motion by wealthy elites in their greed to use the aliens for their own nefarious purposes. The scares of the original Alien are not approached. The crew characters can't hold a candle to the original, or Aliens either, or even Prometheus for that matter.
Honestly, despite the undeniable craftsmanship that went into both movies, the adolescent philosophizing and class-warfare dystopianism doom them. And really, would be impossible to inject a bit of levity here and there. There is barely a smile, never mind a laugh, wedged into all this gloom. I'm reminded of the Joss Whedon quote: "Make it dark, make it grim, make it tough, but then, for the love of God, tell a joke."
In contrast, Thor: Ragnorak was a joke a minute. One thing Marvel has never had trouble with is putting humor into their movies. It is the thing that sets them above the imitators. Ragnarok pushes that capability over into outright farce. There was a thread of a plot here regarding the destruction of Asgaard and a bit of work forwarding the grand epic of Marvel, but it was all in service of the goofy fun. Even the characters changed to fit the script. Thor is not the mighty, noble, hammer-worthy god of thunder; he is hapless and desperate. Loki is not an evil mastermind, but petty and wagish. Hulk is not the uncontrollable beast, but a pouting child. It works because, as I have harped about before, Marvel casts actors that can do comedy. It is their (not-so) secret weapon. That said, it the larger scope of things, it has to be viewed almost like Deadpool: a one-off with little relevance to the big picture. When we get to Infinity War next, these guys are going to have to go back to their old characters (I assume).
And it's not without its shortcomings. Interestingly, the actions scenes lack some snap. They seem a bit pedestrian -- designed to generate still visuals for the posters. The plot is uninteresting and contrived. But that's OK because it was fun. Which is the point of farce: everything is in service of the gags and laughs. As fun as it was, it is ultimately a less satisfying movie that one that hits the killer balance of humor and drama just right. The previous Avengers movies and Spiderman: Homecoming come to mind as just about perfect in that respect.
Now there is a thing a never thought I would say: a movie is too funny. And it's not really, it did what it was supposed to. If every once in while, in middle of a major mythological epic you want to let your hair down, you should. (Trouble with Tribbles, anyone?)
