While this was a pretty fun deconstruction of the genre, and the performances were fantastic, I think the ending just needed a little something. That final scene simply didn't do it for me. We'd already had everything spelled out, so I kind of assumed that there was going to be a twist within the twist but, alas, we simply re-iterated the reveal. Was kind of hoping for something along the lines of "this is all playing out in the mind of an old man who firmly believes that he's a detective". Especially for such a short piece, I think nailing the landing is going to be key.

In any case, I'd certainly recommend it as a fan of the genre, especially if you're interested in picking apart what they're doing and how/why they're doing it!
