actually, you can go wrong as far with it, as you can go with a dilettante, cheap, humdrum movie that was shot for the sole purpose of mass entertainment. these movies starring him as as close to quality as a b-class chuck norris flick (which, at least, were done by rather experienced filmmakers). pretty much the asian equivalent, considering some aspects that are characteristic for the asian and the american cinema.
now you can like or dislike it but that's something one should not forget: that it took asian cinema in general (and jet li pictures in particular) some notable time to become experienced in the entertainment movie industry. and this early lack of experience can be found in the majority of productions of that era and still in many productions of today. for this reason, those asian movies allow for a very interesting approach to cinema: what if you had the right technology at your hand but no experience with the art of movies? would the technology itself guarantee a good movie? no, not at all.
if we see old, silent black and white movies, many of us (including myself) may wonder - why are so many movies of that time so outdated? because the technology was so old fashined back then? no. it's because people had to learn how to tell stories in moving pictures. it is a complicated way of seeing the storyline if you want to show it to the audience as a movie. and for this reason, there are many old black and white films that seem so incredibly ahead of their time - simply because the filmmakers knew how to shoot such a movie. and that's also the reason why there are movies, that can use any kind of modern special effects, and nevertheless appear dilettantish done: because the filmmakers didn't know how to do it.
now this was longer than i expected it to be. but it was necessary to explain that i don't just "dislike" these movies, i just consider them as a necessary but inglorious step in developing a popular art. the reason why american movies are, on the whole, along with the french probably the best in the world today, is a matter of experience in the first place, and audacity in the second place (while, altogether, the latter rather is a trademark of the french productions).
