Hello! I do not know if you sent this ask to the wrong person but regardless, I'm going to react! I love doing these things.

A deep sea submersible having a leak should immediately kill everyone like the Oceangate submarine, and this submersible is missing a good chunk of hull and interior. What should be fished up is a crumpled hunk of metal like a can beneath the shoe of an overeager child. No survivors should be the least of it. But hey it's 2004 and it's science fiction.

Doesn't the operator usually sit at the front of the vehicle? Anyway. Main character got some plot armor I see, no transformation for him yet, though I'll assume his is actually turning into Ultraman. The other guy's transformation looks vaguely crab-like with the spines and ridges that evoke vaguely fish fin-like shapes but they could have gone harder with the body horror to be honest. Why does he still have human ears? Most likely not fully transformed then.

Absorbed...lizards? And used their abilities? Normally, you don't see lizards in labs unless its a herpetologist's. If they wanted to keep the deep sea connection, they should have used octopi. Those little lads are true escape artists. Lizards, beyond being fast and tiny, don't have many abilities that are helpful for escaping what is supposed to be a highly secure lab I think.

Ah. Never mind. Now this begs the question: how did he get those lizards? Those are some very strong Van der Waals forces if they can keep the weight of a modified man up on the ceiling.

To be fair, disabling the camera and lights should have been his first move, and the soldier should have a: brought a friend and b: checked all angles before stepping into the room. Mildly baffled as to where the static came from, since I don't think the humidity from a sign breath is enough to make a camera break, but it's for dramatic effect I suppose.

The guard, if they were still alive, needs to get their hearing checked. The guy didn't drop down immediately and was snarling for a good three seconds at least. Also, tisk tisk, that's a very inefficient way of killing a person. Although I suppose if you're absorbing someone, then it can get a bit messy.

I do appreciate how much more lizard-like the monster got after absorbing lizards, but I honestly don't think the creators were thinking much about having something beyond "spooky monster". I think I'm watching too much TBSkyen but ah, well.

I'm going to assume that this is, at the very least the introduction of a villain. Either a major, Godzilla-esque kind of creature as it absorbs more creatures and acts like a backstory foil for Ultraman due to the two of them having similar origin stories, or it's the start of Ultraman's career as a superhero. Or both. Judging from the fact that it's a movie, I'm inclined to believe it's both. Taking a shot in the dark and I'll say that it'll come down to humanity vs other, both internally and externally.

This got a bit long, but those are essentially my first thoughts. Thanks for the ask!
