From Vegas to Macau feels like a recap of Jing Wong's career, a best-of that harks back to his gambling cinema roots and stuffs in everything Jing Wong has ever done since then, only better. While fun and entertaining, it will inevitably be more enjoyable if you're familiar with the work of Jing Wong and what he stands for in Hong Kong cinema.
Chow Yun-Fat is clearly enjoying his return to the God of Gamblers universe, though he's hardly the only star of the film. Wong also finds some room to launch fresh talent and a handful of nifty cameos. But it's Wong's sense of humor, the crazy pacing and zany comedy that are the real stars of the film.
If you don't like Wong and his antics, it's best to just stay clear of From Vegas to Macau. There's nothing original here, nothing you haven't seen before. But I'm sure you haven't seen so much of it in 90 minutes time. I stopped expecting anything new from Wong a while ago, but if he keeps recycling his own career like this, I'm all for it.
