Video games still have a really long way to go before being considered "normal" (watch any movie that shows someone playing a game and it usually shows them staring slack-jawed at a screen, mashing wildly on random buttons, often with some pre-rendered footage of some insanely gory GTA-esque fake game), but we've come a long way since the '80s when pretty much the only people who played video games were boys aged 8-12.
Movies do that because they're trying to make it's own industry look better than the video game industry.
