Pretty standard stuff here. It was written by Tarantino, so the dialogue is generally excellent, but otherwise it's just your basic drug deal action movie with a stupid one-dimensional "love at first sight" love story thrown in. However, the final act is much more Tarantino-esque than the rest of the movie, and is thus much more entertaining and original, with the exception of the very end, which is absolute Hollywood garbage. Apparently, though, it was changed from Tarantino's written ending by the studio (hint: it's happy now!). Gotta love those guys. The acting is above average, but the girl gets incredibly annoying by the time you get about halfway through the movie with her incessant giggling and toothy smiles. Maybe that's the point, as this is pretty clearly some sort of parody of romance movies, but it's still annoying.
Despite all of this, I was entertained enough to watch it till the end. If you're a Tarantino fan, this is probably worth a watch. It's no Pulp Fiction, though.
In a sentence:
Great dialogue, good acting, average plot, terrible love story, awful ending. But some great Tarantino-style scenes sprinkled throughout. It might be too much 90s for some to handle, though.
