THEME:   none, but few blocks   
GOOD ONES:     Shooter's protection   LENS CAP [not "that" kind of shooter]      
BTW:   Opposite of apres  
 AVANT [oddly 
apres is acceptable, but not AVANT because the former is found often in our language]      
Offended
 outburst   THE NERVE [less an ouburst than an utterance]      
Hardly a warm reaction   BRR [I see BRR as an expression rather than a reaction, like a shiver --- maybe a distinction without a difference]
I liked this puzzle, and all of Barry's, for its challenge, but I find it more an achievement by the constructor than a desire to entertain.      
RATING: 
 
  
   Three grins = Loved it; Two grins = Enjoyed it; One grin = A bit bland for my taste; One teardrop = Not much fun
