The movie definitely seems inferior to the two previous parts. But it is good, still. A good movie on its own, and a very good ending for the "Last warrior" trilogy. I've seen this movie today, and I do not regret a single minute of it.
The biggest problem is the overly complicated plot. So much to happen within two hours! Also, it's a bit overloaded with little details and interludes, that are beautiful and fun, and give us more exposure on characters, yet meaningless on major scale, and thus the main plot line feels somewhat rushed and a bit... scrunched up, I'd say. We see a bit too much of the artifacts to be obtained, and conditions to be fulfilled, and so we somewhat lose connection to the humane side of the adventure, to the nature of choices to be made. In the middle it all fills a bit like a road movie, really. But the silver lining here: towards the end, it all straightens up, again! Another problem is that you need to see the previous parts to fully understand it all. But is it really a problem in 2020-s?
The good things that I really like here are numerous. First, I really like how the plot turns back to the very roots of the main characters, so that we can recall who they are, and who they were, and it matters! I also like jokes here, even though many of them are Russian-specific. I like how they show us modern days in Moscow. I like sound, visuals, I like references, I love plot twists. And how it all ends, I like it, too. It is a good end of the story!
And I'll say it again, I really, really love the actors here! Each and every one of them. These people are so great! Totally fit for the story and the direction.
Now, to sum it up. Not sure if this is really fit for little kids. But for teenagers and adults alike it should be fun. More fantasy than fairy-tale now, still a good adventure, good action and a good story. And of course, one of the best movies of Russian cinema in decades.
The movie is underrated. Go see it, that's my advice!
