Sometimes I have really hard time understanding British humor and "Sightseers" has exactly the kind of dark British humor that I find unfunny. It's probably a cultural thing. I wouldn't say it is laugh-out-loud funny, although there are certainly some funny moments in it. It is an interesting blend of comedy and horror, and the fact that they managed to make it balanced as it is is something to admire about. The performances are solid and the editing is great as well. My main problem with the film is that I didn't like the two lead characters at all; I thought they were selfish, unlikable, and utterly despicable that it made me hard to relate to their love story. Having seen Wheatley's "High-Rise" beforehand, I expected that this film would be also unpleasant and disturbing at times, and it really was often uncomfortable to watch. There are good things in it, but I can't imagine myself watching it again. It's just not my cup of tea.
