There is no doubt that the sense of fear towards the Wraith and basically any enemy that approaches the Expedition members, is gone!
So i say to TPTB, KILL A REGULAR CHARACTER (for good ). Dont kill a redshirt, that does nothing, dont kill a reaccuring, like Heightmeyer, cos it doesn;t leave a long lasting effect, KILL Sheppard, KILL McKay, KILL Teyla, or even KILL Ronin, that would create fear, he is the toughest man apparently.
When the Wraith stun someone these days, it's:
hmmm lets put them in a cell, let them break out and destroy a Hive and escape as easy as you like!
This diminishes an enemy and the show.
I say again:
