Well, there is an outside possibility I was exaggerating a little, but I have watched so many UK crime dramas it is hard for me to remember all the names. I would have to go over to Amazon Prime and look through Acorn and Britbox and all the other UK packages to do up a list. Let's say I have seen 10 or 15 shows, each 5-8 seasons long, 6-8 episodes per season, and they add up pretty quickly. The funny thing is if you finish all the seasons and episodes of one show, and you look for another show, then you pick one and start watching it, you get the feeling that you might have seen it before, but maybe not because they are all basically the same. The other funny thing is a lot of the time I can't understand what anyone is saying because they mumble with a heavy accent, particularly the ones set in Scotland. Sometimes I turn on the subtitles; otherwise there is no chance I'll be able to know what is going on much less figure out whodunit.
I started watching one last night that I can't remember the name of. I had to stop watching it because these guys all got drunk at a stag party and as a joke buried the groom alive in a casket with a walkie-talkie and an air hose, and then had a car crash, and three of the of the guys died and the other guy is in a coma or whatever, so nobody knows they buried the groom alive, they just know he is missing, and a guy who lives in a caravan park picked up the other walkie-talkie at the crash scene, so he's the key, but he doesn't look like he is too high up on the intelligence scale so that's going to be a problem, etc. Anyway, I am a little claustrophobic and figured I was going to have nightmares about being buried alive, so I turned it off.
So anyway, maybe caravan parks are all Camelot and there are surveillance cameras all over the place, but that's not my impression. And the only guys who have shotguns are the rich guys that have hunting parties on their estates, in which case the murderer is probably the old guy that takes care of the estate and has the gun safe in his cottage and is probably the brother of the guy who inherited the estate because their father had an affair that nobody knows about until they read the will of the guy that was murdered and all is made clear.
And you thought photography was complicated.
