List your personal dumbest trailer trends...
Mine are:
1. Inception "BROOOOOOM!" following by constant fade-outs. It wasn't that cool when it started and it's not cool now, just really annoying.
2. Stupid slow versions of classic songs or some crap like Lorde over action footage (Last House on the Left, early Suicide Squad, Dracula Untold, A Walk Among the Tombstones, Age of Ultron, San Andreas, and way too many *beep* others to count). It was ALWAYS lame and they ruin almost every recent trailer out there.
3. Stupid piano versions of classic movie themes (early Rogue One, Ghostbusters): This is not too bad IMO, but it'll be annoying if they keep doing it.
Feel free to add to the list, in honor of IMDB's final days and all, lol.
