I think I did irreparable harm to my brain.  And that was only from watching the premier of Riddick.  FUCKING AWFUL and a travesty to Riddick fans everywhere.  Here is my plot summary:
Riddick, a collossal hero who came to rule the Underverse quite by surprise suddenly finds himself as an old, washed up, broke, B-rated, out of breath, out of shape, Hollywood hanger-on.  His misery, not being quite sufficient for suicide, spurs him to make a sequel to 3 of the best sci-fi films made in the last decade, so that no one may doubt whether he is indeed flogging a dead horse if ever he should make another.  This is the end of the franchise, and there are no fine points to be put on.  By comparison, Star Trek V was a springboard, and that fact that it had sequels does not take away from the feeling of the end of the Star Trek franchise conjured up by its actor-turned-director.  Yeah, Escape from LA was a relative new beginning, and Highlander can make a comeback after those flying vampire twins...  The biggest battle this old Riddick has up his ally is a daily wrestling match with his geriatric diaper.  What a fucking letdown.  I could only every stand VD as Riddick, and now he will forever be the guy who also starred in the worst movie since Starship Troopers 3.
