I'm such a huge Clue fan, I really did love most of the interviews with people directly involved with the film. I wish there had been a couple more interviews like that with cast/crew members vs. Convention clips. Overall it needed a tighter edit, even with the existing interviews.
The second half really started to wander, and I think that is where the film struggles with its identity. Some of it is very much a documentary, but other parts are more of a vlog or compilation of the cult impact. It should have focused on being one thing. I think it would have been wonderful to have short clips of fans quoting their favorite lines or saying what so inspired them running underneath the closing credits. But too much time was dedicated to interviewing content creators I've never heard of, soundtrack companies, or the filmmaker reading from the Clue storybook at the end which was unnecessary. It felt like filler.
So I'll give it a decent rating for the interview content it did provide, but it needed more focus and better editing to be the kind of documentary I wanted for Clue.
