honestly season 6 is better than 4 or 5. but at this point the standards are so low its hard to tell. this is the shortest season, at only 13 episodes so the newbies here thank goodness were not ruined.

top episodes:

The Hurt Locker 2;
The Rise and Fall of Sue Sylvester;
Homecoming;

bottom episodes:

Transitioning;
Dreams Come True;
The Hurt Locker 1;
