I am reminded why I don't regularly watch "Grey's Anatomy" by the bloodbath of its season finale, something of a tradition at the show. Shonda Rimes and crew like to shake things up at season''s end, but lately it's been particularly anoying how willing they are to bring in sensationalistic plots or ready-made disasters, all while the characters continue to banter emptily in a one-size-fits all clipped, slangy style.This year it was a guy with a gun who was unhappy at the terminal treatment of his wife. He goes in and starts shooting randomly, but there's no hospital security force or others to track or subdue the guy. Even when he's outnumbered in a room, nobody thows a bedpan at his head or otherwise tries to gang up to subdue him. Instead, they let him prattle on and shoot people. What's with these Seattle cops? They're on the scene for hours and are just starting to enter the building as the episode ends.
