I'm going to suggest two sitcoms and you're going to "politely discuss" why one is better than the other.
Comedy or art may be subjective but putting that aside, what makes your favourite better than the other? Is it the writing, acting, direction? Is one outdated, is the other timeless? What was it about the writing, what did it say and will it always be relevant?
If anyone starts getting personal I will void your comment and if it becomes too much will close the thread and push poo through your letterbox.
We'll start off with a classic blood boiler:
Fawlty Towers VS The Office.
