I watched it on the heels of Doctor Strange in the Multiverse of Madness, which I thoroughly enjoyed; and this - in several senses, a very similar flick - blew it out of the water.
It's certainly sentimental, but I think it earns its right to be. The hotdog fingers multiverse and the buttplug kung fu battle are so bizarre that a little cheap plotting seems like a fair price to pay. Michelle Yeoh is great.
Finally got to see this, and enjoyed it a lot. The Chinese family stuff holds very true to what I see/hear in my wife's family. Interesting about Jackie Chan, we noticed Ke Huy Quan was moving a lot like him in the martial arts sections, very much that style.
I also read that the fella playing Gong Gong (James Hong) is 93! Blimey. He's a man with a long IMDB credits list.
