This movie seriously good to the extent when you leave the theatre you really feel like you forgot everything because every fight sequences are so well made that you literally can't figure out what was the main coolest moment from the movie that you can pick out.
The first time you lay your eyes on the characters and backgrounds what you would immediately notice is the "Lighting". I can't even describe some frames look too damn good. Absolute wallpaper material that's how I'd like to describe it.
The fights are vibrant and impactful. The characters pull out such movies time to time that your brain can't figure out what did it just saw.
The really nailed animating the castle. The way that the camera moves across the castle looks to damn good. They perfectly managed to create the atmosphere that looks beautiful but equally terrifying. The way the single sound echoes across countless structures adds to that eerie feeling when you see it.
The way the characters fights across the castle obliterating everything in their path along with beautifully composed music gives you goosebumps.
In order to give your time to process things there are minute flashbacks time to time for the first two fights which add to the emotional aspects.
The main longer backstory of Upper Three is the main highlight and won't feel dragged out (which most people are complaining about) if you have thoroughly watched the entire previous seasons. If you have did so, you are going to love every last bit of it.
I'm strictly recommending people to watch the previous seasons before jumping into this movie. If you don't, you are going to still love this movie and it's action sequences but then the backstories will obviously tire you up because you haven't developed than emotional connection with them through last seasons.
This movie is a masterpiece. It did everything way better it was intended to. (10/10)
