Let me preface this by saying I watched this with my partner for a date night.
I am a regular watcher of NerdCubed, but do not watch Ashens. My partner has not heard of either youtuber.
The opening 20-30 minutes of the film were a bit slow and choppy feeling, like it was edited and changed quite a bit, but once you got into the 'jist' of it, the movie took off and it was PROPERLY hilarious.
Thinking I was impartial to it, I asked my partner and they loved it as well. If you enjoy dry British comedy, and nerd culture, this is a MUST watch.
There were quite a few points where both of us burst into rolling laughter on the bed. I even imitated a certain "lawn-mower" scene for them later that night as a bit of a cheeky joke.
Overall, WATCH IT. it's 8 bucks, it supports individual creators, and it's a proper laugh.
