The following is an opinion on perhaps the most overrated show to ever grace British TV...
I have a group of colleagues who never stop quoting Monty Python (which is pitiful in itself). They are obsessed with the show/movies and constatntly tell me I'm 'sad' for not liking it.
Here's the thing: I've watched Python when it used to be on all the time on British TV. I even watched the spin-off films too. They just aren't funny. Not one bit.
I watched Life of Brian and Holy Grail and almost fell asleep because they bored me to tears. I've noticed one thing with the Python team: they try too hard to be funny. As a result, the 'comedic' deliveries look forced and unnatural, and, therefore, not humourous at all.
Genuinely funny comedy (British) would be the likes of The Office, Blackadder or Only Fools and Horses. These have good writing, excellent delivery and are sheer brilliance.
The only reason people like Python is because they're trying to impress their friends that they have 'sophisticated' wit (aka 'I don't find the sketches funny but I'll pretend to because that means I'm cool, right?').
I can't think why anyone would find Life of Brian or Holy Grail funny and it is disgraceful these films are listed in the imdb top 250. Then again, the list has films like Kick Ass and Inception amongst the 'greatest' films so it's hardly surprising a lot of weak movies make the list.
Anyone who claims to enjoy Python, in my opinion, only does so in a pathetic effort to impress their peers. Which is disgraceful.
