Nice, except for the schools group - faaaar to difficult to spot, especially given that one is a two-letter acronym, one is a three letter acronym.

Thanks, for what it's worth I agree, I was honestly struggling to come up with something for the last connection so it was admittedly a bit of a cop-out!

The tricky subject group is forgivable - gettable without spotting what they all are even

Getting the name of one of Kubrick’s best known films wrong is not (it’s 2001: A Space Odyssey) - just to fit it as a red herring in another group. Dr Strangelove lacks part of its name too (it’s really Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb,) but more commonly, if incorrectly, shortened to Dr Strangelove . Full names or part names for them all would be ok I guess - but abbreviating to 2001 in a grid full of dates is just a cheat…

And that’s what I didn’t give it five stars …
