If you want proof that the Marvel Cinematic Universe sucks the creativity out of good directors like a Hollywood vampire, watch “Freaky Tales.” Directed by Anna Boden and Ryan Fleck, who helmed 2019’s lifeless “Captain Marvel,” their latest movie has, um, flecks of the supernatural heroism and urban vigilante justice that we associate with the comic book genre. However, unlike many of those bland caped behemoths, “Freaky Tales,” which had its world premiere Thursday night at the Sundance Film Festival, also boasts enough forceful, nerdy personality to fill the San Francisco Bay.
