This is just Swamp Thing but the focus characters aren't the interesting part of the story.
Imagine a Swamp Thing story focusing on a killer.
Great, now make the point of view character... not Swamp Thing.
Now throw in some murders. Make sure they're pretty much entirely off camera or framed in such a way that we don't have to do much full-body cgi, because it's clearly the entirety of the budget.
I know Swamp Thing is no stranger to murder, but he always at least had a mind (well, not really, he was a bunch of plants inhabited by the green who took the imprint of the thoughts of a dead scientist, thinking they were the scientist) but here it's just the same as your standard "Sharktopus" or "Mega Python".
Watchable but I just can't get over the clear fact that this is just "what if Swamp Thing was mad and not very interesting"
