Pretty good comparison as most of OW players are casuals.

Still, the game's had a ton of improvements over time, whereas movies aren't a live-service thing, bit of an apples to oranges comparison.

The game itself has remained popular because it's received tons of updates in that decade, not because it was perfect at launch. Case in point: playing it's original build during events is not fun for long, and most players stop bothering very quickly.
