Brightburn ★★½

Now we know what a comic book movie directed by Lucio Fulci might look like. So gory it would've gotten an NC-17 under normal circumstances, this is a tonally messy and ultimately nihilistic oddball of a film with a handful of effective moments and a really nasty attitude, much like other modern killer kid movies like The Prodigy, Goodnight Mommy, etc. The end credits are actually more entertaining and inventive than the main movie, so if they get around to that sequel they've been teasing, it should be... interesting.
