One of the few Taiwanese directors who made it in the US. Personally I'm not a big fan of Lee's overly sentimental and often garish style, but he's proven himself a popular director in many genres, so at least he's worth a try.
Eat Drink Man Woman
Plot, sci-fi elements and drama all are kind of mediocre, but the film has a handful of truly outstanding action scenes that make it very watchable indeed. The CG to create Smith's younger self isn't flawless, but isn't really distracting either. A pretty decent blockbuster, especially with Lee directing, but nothing truly great.
Life of Pi
Crouching Tiger, Hidden Dragon
The Wedding Banquet
Early Marvel film, directed by Ang Lee. It's an impossible match of course, as a result the film is terrible. Lee lacks the skills to make a fun and frivolous superhero flick, Marvel lacked the budget to make it at least some kind of technical feat. It's long, badly acted, boring and way too serious.
