I LOVE Punch drunk love (it's no Boogie nights but it's insanely underrated) and I admit Sandler's performance is great in that movie but we don't know how much of that was due to careful editing, shooting twenty hours of footage then picking the three minutes Sandler didn't come across as a douche etc. I'm not saying he's definitely not got it in him to be a good actor but I wouldn't give him too much creative credit for Punch drunk love. Remember how, after Pulp fiction came out, we all thought Travolta was cool for about a year or so? Then Broken arrow and Face off and Battlefield Earth (shudder) happened and we realized Tarantino had just been an even better director than we'd credited him for.
No, Shooter McGavin was much more than angry. remember how happy Shooter McGavin was when he heard about the how well the heckler Shooter McGavin hired did? Or Shooter McGavin's great pleasure in ordering Shooter McGavin's custom fit ugly jacket with one sleeve slightly longer than the other? And how about Shooter McGavin's absolute fear when Jaws was doing a horrible job of fake chasing Shooter McGavin after Shooter McGavin stole the jacket from Happy? Shooter McGavin is far more complex than just angry. So a concerned Shooter McGavin weatherman who discovers the approach of the perfect storm which will leave a luscious Diane Lane single is not a stretch at all for someone of the caliber of Shooter McGavin.
