Recency bias. There’s always been good video game movies and shows, mixed in with bad ones. Most basic example: the Tomb Raider movies were pretty great (for their time). Pokemon has been running so long that people have forgotten it was created as a cross marketing opportunity to sell the game. Mortal Combat and Resident Evil are always overlooked. Hell, even the super campy Street Fighter movie is fun.

My personal favourite is Steins;Gate.
