Siegel™’s review published on Letterboxd:
Relentlessly hopeless more than frightening, more gross-out gore than genuine thrills. There's an overall feeling of desperation rather than terror, frustration more than fear. Filled with bursts of bloody insanity but other than what the violence might make it seem, Inside seems to be trying to say something more than your average genre slasher; I just wish it was a little more clear on what that something could possibly be. I highly recommend just for the sheer level of INSANE this is willing to go.
