Here's the deal ... Bill's the lead in a remake of the gothic cult classic hit movie from 1994 -- and the first pictures of his revamped "Crow" character just dropped Wednesday via Vanity Fair. There's a lot of set photos they have ... but everyone's focused on this money shot.

FYI ... "The Crow" follows a murdered man who comes back to life to enact his revenge against the men who killed him and his fiancée -- which is it has this dark, noir-esque vibe. The whole film is basically a fantasy revenge flick ... with memorable makeup/costumes.

In the OG film, the eponymous character -- played by Bruce Lee's son Brandon -- wore black leather jackets and bodysuits, and white face makeup made him look more like a corpse, but overall his look was pretty understated ... especially when compared to Bill's version. That's how the internet seems to feel about it anyway!

Just check out the pics ... Bill's got the leather and white face/body makeup -- as well as a series of unseemly and sorta cartoonish tattoos ... including a giant eye in the middle of his chest and the word "Lullaby" written above his right eyebrow.

All of these tats have fans thinking about another outlandish character look ... namely, Leto's Joker in "Suicide Squad" who literally had "Damaged' written on his forehead -- just so the audience wouldn't miss that particular character trait, we guess.

Point is, fans are super upset ... with some even going as far as saying this concept of the character spits in the face of Brandon's memory.

If you don't know ... Brandon was actually shot and killed on "The Crow" set after a prop gun fired an uncleared bullet fragment from a previous scene at him. No one was criminally charged, but his mom Linda Lee Caldwell successfully sued filmmakers.

Safe to say ... fans are pretty protective of Lee's character and his legacy -- and they're pretty sure Skarsgård's look is only going to hurt the memory of Brandon and "The Crow" -- that's what some are saying about this.
