Pretty much sums it up.
I use my knowledge of future deaths in the series to keep people in line.
Nothing worse than a spoiler to shut down peoples dickishness
Except some series that got the idea from books but did something totally diferent with the plot line (example: vampire diaries, pretty little liars, the secret circle, gossip girl)
The Percy Jackson movies (esp the 2nd one) drive me crazy!!!!!!!! I mean... How come Luke can walk on the sea like Percy?! So now everybody can walk on water now?!!!!!! *face palm*
