Much as I'm loathe to watch an MCU film, I had some interest in Shang Chi in part because of some of the talent involved, it was one of the last films noted action director Brad Allen worked on before his untimely death, a man who worked with Hong Kong performers and had been the first non-Asian member of the Jackie Chan Stunt Team, and besides veteran performers like Yeoh, Leung, Yuen Wah (among his many roles, the giggling Vietnamese general in Sammo Hung's Eastern Condors and the landlord in Stephen Chow's Kung Fu Hustle) and playing Death Dealer, martial artist and actor Andy Le of the troupe calling themselves Martial Club, who've posted various shorts and sketches on their Youtube channel, and they are some interesting talents to watch.
I see what they're all going for, especially in the second half of the film which seems to take cues from wuxia epics as well as fantasy martial arts films in the vein of A Chinese Ghost Story but despite all of the talent involved it's all coated in a thick layer of MCU "humor" and editing and CGI that smothers anything that might be a tad different or interesting from the established MCU formula. Awkwafina's performance however fits in too well with the Marvel movie formula, as she spouts off one-liners on the same level as every other "Uh, that just happened" and "they fly now?!?" and the "I guess you are wondering how we got here" level gags you've heard in various other big, blundering CGI blockbusters. Calling her performance "nails on a chalkboard" is inaccurate because actual nails being dragged across a chalkboard right now next to me would be a lullaby compared to the unfunny winking at the audience humor that she makes even worse.
