One day I’ll do that “ABBA Voyage” story where the holograms come to life and start killing people. That’s the best idea ever.
Uh, The Banana Splits movie? Willy's wonderland? The Five nights at Freddy's adaptation?
Granted, if they have to bend concepts to avoid copyright issues, why not give ABBA a bit of KISS spice. That should sell the threat a bit more?
