I watched Winners & Sinners last night, and it was the first time I was disappointed by an 80s Jackie Chan movie.
It's the first of the "Lucky Stars" series with Sammo Hung directing and starring with a group of other HK actors who went on to star in several sequels. Yuen Biao also gets top billing on the box art.
Every second Jackie Chan is on screen is a delight, but that highlights the problem with the movie: he really isn't in it much! Yuen Biao is in it even less, with only one small scene. Sammo Hung is great when there's action, but most of the movie revolves around humor where he's hanging out with his friends; the humor is generally dumb and slapsticky and doesn't really hold up that well. Overall, the movie has about 25 minutes of really good stuff with 1 hour and 20 minutes of very bland comedy.
I'm glad I watched it because it's very significant for HK cinema as well as for the careers of Jackie Chan and Sammo Hung, I guess Yuen Biao too. But it sure doesn't feel like much! I'd recommend Wheels on Meals or Project A instead. I got the first three movies in the series as an imported blu-ray set; I'm hoping the next two are a bit better...
