Only Quentin Tarantino could make a film like The Hateful Eight. For that matter, nobody else would even be allowed to make a film like it.
The bad news is that Oldboy is a typical pointless American remake. The good news is that it's a decent one--not remarkable, but at least entertaining, particularly if you can keep yourself from constantly comparing it to the original. Which, let's face facts here, you're not going to be able to do.
