My Plex account listed this movie as being a "Drama Romance Crime Thriller Horror Comedy". We laughed, but that's actually pretty accurate.

Final rating:★★★ - I personally recommend you give it a go.

Wheaton pulls off this black comedy well. It is a quiet crescendo of unpleasant characters justifying their anti social actions with the logic internal to their own moral micro-cosmos. Watching Sightseers is an experience of being torn between being amused, feeling guilty for being amused, and repulsion against the protagonists and even most of the minor character that has the misfortune to cross their paths. Do not watch for feelgoods. Watch it for feel-urghs. But do watch it because it is worth a watch.
