Sympathy For Mr. Vengeance is my favorite. I love Oldboy--it's still one of my favorite movies and introduced me to Korean cinema--but Mr. Vengeance's plot seems a bit less contrived.
2-0-Sixx, you'll have a hell of a time finding hardcoded subs. Are you familiar with Matroska video files (MKV)? They often come with subs in the video file itself (rather than in a separate sub or srt file.) This is preferred to an AVI with subtitles burned onto the video itself. In my experience, MKV are usually used for movies in HD. The problem is that since these files are so big (usually between 4 and 6.5gb for 720p rips) they usually require more download links and, ideally, an account to some file-sharing site.
I can give you links for this. I can also give you dvd rip links with subtitles in a separate file. At least you wouldn't have to go search for subs. All you have to do is name the subtitle file the same as the movie and keep both in the same folder. Then play the movie with VLC Media Player, which is really the best media player around. I believe the subs should auto load if you follow those instructions. But if I am mistaken, just click the video tab at the top of the player, and you'll see "subtitles" on the drop menu where you can select them.
Anyway, let me know if you want any of those links. Rapidshare and Megaupload are common ones I can get.
