In your improv classes, Stu, when you're asked to give feedback on a scene you watched, what does the teacher say to you when you answer, "I liked it," or "It didn't work for me"? He or she says, "What did you like?" or "What did didn't work for you?" Don't answer, I know they do, I've been there. You can't have a dialogue about a scene unless you talk specifics. Just saying something is bad, bad, bad is nonsensical.
Drunk uncle? No. The playwriting professor about whom everyone says, "God he's an asshole but I'm learning a lot," that's me. Just be glad I'm not teaching sketch writing at wherever it is you're studying.
As always, there's an en point Python reference at hand: "I came here to have an argument." "No, you didn't." "Yes, I did." "No, no, no...."
Duly noted. I typically write my comments almost 24 hours after the show has aired, so on occasion I'm too tired or distracted to fully express my thoughts. A day or so later, I look at an EDT and wonder (for example) "why didn't I comment that on that weak 'Santa Barbara Action News' sketch? Everything about Fred's character felt like a crutch or a rehash, and the ending was too tidy."
As for the recent dialogue in this forum, I encourage debate but I draw the line at sudden topic changes, namecalling, or character assassination. It is a discussion board after all, and even though I moderate the ongoings I lay down the law when I have to. In turn, I can also be quite perfunctory.
