If it's a movie you really liked or was really good, I could see keeping the ticket as sort of a keepsake memento item.
In the case of Silent Hill, I simply could not wait
to rid myself of that ticket and any shred of membrance of the movie's awful, awful wretchedness. I collect many, many Silent Hill things, from very rare to common items that I deem worth having to own and keep.
The movie ticket............is not one of those items.
