Remember when Legendaries were mysterious and thinly characterized creatures the player knew little about? They were always optional and just served as proof of a trainer's skill and dedication then.

Seems like nowadays they have sunk into a sad pattern of lore-overload, forced encounters with "faint or capture to continue" mechanics, and not even the semblence of a dungeon as a hurdle to obtaining your legendary. I can honestly say I feel bad for the children of today.
