She is fucking trying to murder you. Tatl is annoying, but she doesn't try to kill you by jumping out in front of you and stopping you from dodging an oncoming freight train.
Seriously, just played through the Jabu-Jabu level tonight, and right as I try to dodge damn near everything, she interrupts with a prompt you can't fast forward through - several times a repeat of a past prompt - and then returns me to the action with the enemy striking me but my dodge button presses lost. That isn't an accident, the little winged ***** is intentionally trying to kill me.
Side note from selecting the "Current Mood" - the emoticon for "Homicidal" is a blue ball with a knife. Even DA knows Navi's a murderer.
