I'll start by saying that if you're looking for a great story, you'll be disappointed. Shang-Chi is a pretty standard hero's journey at its core, which is a shame because the story could have been inspired by House of Flying Daggers and other wuxia titles.
So why a rating so high? Because where the story falls, everything else excels.
Shang-Chi is visually spectacular and a real treat for the eyes with some visuals that are incredibly distinct for the MCU. In regards to aesthetics, Black Panther walked so Shang-Chi could run a marathon.
The fight scenes are all amazing. There's one weak fight, but it's meant to be weak, and they're all very long, which is great to see. One of the early ones went on for a solid 5 - 10 minutes, which was unexpected but far from disappointing.
The first actual fight scene is my favourite in the MCU, and I was worried none of the others would top it, but they were all delightful to watch, and I was so glad they did a parallel of it later on. Either way, the writers went hard on the fight scenes and that paid off.
In summary, the story is lacking, but I'm glad in a way because that allowed everything else to shine. And shine, it did. I hope future directors take lessons from the aesthetics and choreography of Shang-Chi.
