Hibi Skus’s review published on Letterboxd:
Such a mess. :(
I fell asleep after one hour, so I guess that's why it's called The Big Sleep... It's impossible to concentrate. I had no idea what the actual fuck was going on, too much characters, I just stopped caring about it. There's not a single character in this movie that you could care about in any way.
I didn't finish watching it, didn't even googled the ending 'cause I don't care. Gosh I feel really frustrated right now... I just got a headache watching this film.
