You can view the film in three ways:

(1) U.S. English Language Dubbed Version - everything is dubbed in English.

(2) U.S. Unrated Version - half of the film is subtitled, and half of the film is dubbed (which is how it was released in theaters).

(3) Original French Language Director's Cut Version - everything is in French.

The film itself is the same no matter which version you choose. The only problem with choosing the Original French Language Director's Cut Version is that the subtitles are not entirely accurate. There were lines added in the U.S. English Dubbed Version, so if you choose to view the film in French, the English subtitles will sometimes display lines that are not being said by anyone.

For the theatrical release the film was rated R by the MPAA. To achieve this, the film had to be cut heavily. More than 1 minute of violence is missing in different scenes. A detailed comparison between the theatrical version and the unrated version can be found here.
