The bad part is the overall film, the story is half hearted and looks like it was written on a napkin over lunch, and it is very dull and poor. If you watch it for the story then it's dull.
The good part is the incredibly imaginative cinematography, with a huge range of innovative and brilliant filming tricks. The music is well chosen and adds to each scene beautifully.
There are a lot of odd techniques used, like switching between black and white photography to colour and then back again, and insertion of animated parts, all done quickly and in keeping with each scene. The editing is sharp and keeps each scene going at a superb pace. I tend to think this is the young Mr Tarantino flexing his directing skills.
Quite a mixed up film, and if you love cinema then viewing this is a must if only for the ingenious use of the medium.
