Considering that exploitation films are a superset that includes several genres of horror movies, yes.

I don't know about many still image movies, but La Jetée is pretty respected. So if it can even be called a genre, it does not seem to be especially disrespected.

Exploitation is movies like the infamous "Ilse" which mixed Nazi-fetchism, sadism, torture, castration - basically wallows in the most taboo subjects imaginable.
