The obvious joke here is that "Mickey 17" is not as good as the original "Mickey" but better than "Mickey 16". Obvious would be an appropriate way to go because that is what this movie does, make obvious every point of view that the director has. Bong Joon Ho has made a screed about the economic issues he sees as being wrong in the world, and he has populated it with a mix of cardboard cit out villains, environmental wonkiness and odd visual touches. The movie still looks like a big budget science fiction action film, but it is one of the most unengaging films I have seen in years.
Robert Pattinson, plays the titular character as a naïf, lost among a crowd of zealots who are slowly losing their patience with the circumstances they find themselves in. It is only his innate ability as an actor, that allows the character to work as much as it does. The script really gives us no reason to care about Mickey, other than the fact that he is the central figure. There is a supposed romance as part of the story, but it happens so fast and seems so perfunctory, that when it is threatened, we really don't care.
The biggest problem I had was that the tone of the movie changes inconsistently. Certainly the comedic elements are important, but they are off, like a comic with good jokes but bad timing. The humor needs to hit a little bit more quickly at times, and then move on. Too often the comedy feels drawn out as if it is a sketch on SNL that would have worked as a three minute bit, but has been given an eight minute segment to fill. The parts that rely on Pattinson are the most effective, unfortunately, Mark Ruffalo and Toni Collette keep showing up and spoiling what might have been amusing. Their cartoon characters are not funny, but obnoxiously irritating. Both Ruffalo and Collette are fine actors but they are being directed to over the top performances which are not funny. The strident parody of privilege is so on the nose and exaggerated that it cheapens the film. 
The opening act should give us more opportunities to see the lives that Mickey is burning through, instead we get a montage that illustrates the points and uses up all the humor from the premise in just a few minutes. Also, I know it may seem strange to look for a logical explanation for why something happens in a film like this, but suspending your disbelief can't work if you are going to break your own rules. Mickey 18 either has a defect, which needs to be explained, or the script just doesn't care about characters, only stereotypes.
By the time we got to the third act conflict with an alien species and the maniacal cult leaders, I just did not care anymore, and that was with forty minutes at least left in the film. To say that this movie was a disappointment would be an understatement. I thought "Snowpiercer" was over praised but "Parasite" was deserving of the accolades that it got. This movie will probably develop a cult following of it's own. All those people who are fans of bad movies like "Lifeforce" where you can see the potential but the execution leaves you scratching your head and asking "How did this get made?' should enjoy watching this over the next twenty years, I just wish I enjoyed it the one time I've seen it.
