This movie manages to be both amusing and features some really impressive fight sequences, despite being noticeably flawed in its production. I wasn’t familiar with Jackie Chan's work before seeing this one, though I recognize him from other projects. The story centers on a friendly young man from Hong Kong who travels to the United States for his uncle’s wedding; his uncle has been living in the Bronx, New York, for quite some time. During his visit, he discovers that his uncle plans to sell his business and retire to a ranch, and he'll also have to deal with a biker gang and a mafia group searching for a bag of diamonds that ended up in the possession of Chan’s character. Naturally, things will culminate in a brawl. The film succeeds at its straightforward goal of providing entertainment. There's a good balance between humor and action. The jokes are simple, but they work well, lending the movie a familiar and welcoming feel without veering into overly sentimental territory. The fight scenes are definitely the highlight; it’s worth watching Chan take on ten or twenty opponents at once, showcasing his martial arts skills. However, it's important to acknowledge that the film compresses the timing of these fights, which enhances their impact but sacrifices a sense of realism. Chan is very likable and perhaps more approachable than many other actors who built careers on tough-guy roles like Van Damme or Chuck Norris. He deserves praise for both his performance and his fight choreography. Unfortunately, he’s the only actor who truly stands out because the rest of the cast feels quite inexperienced. But let's be clear: Chan isn't trying to deliver a dramatic acting showcase; he does exactly what’s needed—being funny and fighting well. It’s Jackie Chan, not Lawrence Olivier. Anita Mui and Françoise Yip are present seemingly just for their appearance. The script is rather weak, serving mainly as an excuse for plenty of comedy and action to suit various tastes. The writing is so thin that you quickly forget the characters' names and why Chan came to America. These questions soon seem unimportant—or, more accurately, were considered unimportant by those who made the film. The villains are underwhelming; the mobsters appear frightened, and the biker gang is laughable. However, these shortcomings are somewhat excusable considering the poor editing job. The cuts are jarring and out of place. Some scenes feel abruptly inserted, while others pop up or end suddenly, mirroring the movie's abrupt conclusion that feels more like a television episode than a theatrical film.
