Bits of Sunshine, Interstellar, Alien, Coherence, Event Horizon, Saw, and a load of others mashed up into a fairly underwhelming package. It never gets really smart but at the same time is kind of incoherently written and presented, with a mishmash of tones and story threads that doesn't really work.

It's a sci fi with bits of horror/gore, and bits of comedic relief, and a troubled protagonist that's reaching out to the edges of our universe, whilst trying not to lose their connection to the earth they left behind.

It's really lacking the sense of spectacle and awe that the movies it's aping have. There's a few neat visuals, but much of it is very conventionally shot and directed.

Feels just like a bunch of different elements tripping over each other, and never forming an interesting or creative whole.

You can super tell they just got another existing script and packaged it up as a Cloverfield movie, and everything tying it to the greater lore is just twaddle. I thought the bits trying to connect 2 to 1 were the weakest part of the second, but at least it was just like a prologue and an epilogue. Here it's littered throughout, but don't bother paying too much attention, since it doesn't pay off in a meaningful way.
