What is a self-indulgence movie? If you have foot fetish, you have so many bare feet scenes, that's self indulgence. If you like to objectify women, you have every scene with women in it be either taking from 'elevator view' or 'rear view', that's self indulgence. If you like violence, you have to 'squeeze in' the unnecessarily violent faux climax, that's self indulgence. If you don't like Bruce Lee, you have him literally look like a clown, while the real Bruce Lee is nothing like that (just watch a documentary or movie to see for yourself), that's self-indulgence.

This movie does have its merits. I actually like the slow boiling pace for the most part, although the overuse of still-move-still-move to make a false sense of tempo is pretentious (and yes, self indulgence). However, any new wave movie would satisfy my taste in slow pace/nonethingness, and most of them are actually better at achieving this.

It's not bad. It's just self-indulgent at its most.
