Scooby-Doo! and KISS: Rock and Roll Mystery (2015)

Scooby-Doo! and KISS: Rock and Roll Mystery is the kind of crossover that shouldn’t work this well, yet it somehow hits like a power chord—mixing classic Mystery Inc. sleuthing with a gleefully over-the-top rock opera vibe that’s colorful, funny, and surprisingly spirited. The movie leans into KISS mythology with psychedelic visuals, playful satire, and enough musical energy to keep the whole thing bouncing even when it veers into monster-movie theatrics. It’s still a Scooby adventure at heart—jokes, chase sequences, and a mystery that knows how to keep kids engaged—just with bigger hair, louder guitars, and a Halloween funhouse atmosphere. If you prefer your Scooby stories grounded and low-key, the cosmic rock-fantasy swing may feel extra, but if you’re even slightly tempted by the premise, this one commits hard and makes it a blast.

Scooby-Doo! and KISS: Rock and Roll Mystery is clearly trying to be a loud, kid-friendly Halloween romp that doubles as a love letter to KISS, complete with big fantasy stakes, trippy visuals, and plenty of music. The catch is that it often feels less like a mystery and more like a branded theme-park ride—lots of spectacle and jukebox energy, not much classic clue-chasing payoff. If you’re not already amused by KISS’s over-the-top superhero personas or you prefer your Scooby stories grounded and spooky rather than cosmic and chaotic, this one may test your patience. That said, the animation is punchy, the set pieces move fast, and older kids (or KISS fans) might have a genuinely fun time with the sheer cartoon excess.
