The trouble I find with anything I come up with is that I instantly think, would people compare it with XXX? This may not relate to the context itself but the base of the synopsis and also could not be just compared to TV series.
For example, any mockumentary will be compared to The Office and Operation Good Guys, any space show will be compared to Red Dwarf and Hyperdrive, any show about radio will be compared to Alan Partridge and Smashy and Nicey, any show about a promotional company will be compared to W1A and (the excellent) Reluctant Persuaders, any police show will be compared to Naked Gun, Top Coppers, Reno 911, The Detectives etc.
What you have written straight away says Inbetweeners and Men Behaving Badly to me. I love both those shows and, to be painfully honest, your ideas don't come near. Also, didn't BBC recently have a series about unknown parentage following a threesome?
I really think that there is a market for a UK gross-out comedy but it needs to be better than and completely different to Inbetweeners and Men Behaving Badly. Maybe once you have fleshed the ideas out into actual scenes, my opinion would be different.
Please do not think I am being over critical. I am just saying what I would apply to any ideas I have and, to be honest, have discarded lots of ideas as I could not guaranteed they would be thought original enough.
Just to give one example, an idea that milled around my head for a while and actually got as far as one and a bit episodes being written, was an average husband and wife, both working but struggling to make ends meet, with a couple of argumentative kids. He wins the lottery but tells his wife that he had uncovered a serious flaw in a major web site and they rewarded him heavily as it would have cost them millions. However, the figure he gave was a lot less than the lottery win (most of which had been moved to a secret account) but enough to set him and his wife up in business. The wife being non tech savvy would have not seen how ridiculous this was.
The story followed these, fairly common people, now living on a relatively posh estate. The wife has her own Hair/Nails salon which she works ridiculously hard to make a success. The husband set up a web design company which he barely has a passing interest in, other than for personal projects. He has only set it up to make his wife thinks he is out at work every day. When he does go to the office he is is more of a hindrance to his staff, but most of the time he has sneaked back home or somewhere else.
They are in their 40's, quite abusive to each other but in an affectionate sort of way and both openly flirtatious with other people even in front of each other. Now that the kids are in their teens, they are also quite intolerant of them.
So there we have it. My idea that would be compared to, or accused of being a rip-off of, My Family, Outnumbered, 2Point4 Children, Married with Children, The Good Life, Modern Family, Bread and many others. The story is nothing like any of those but as it is based on a family, comparisons will be drawn so I get myself thinking, can I ensure this will be better than those?
