1714 set very broad

All sets very broad, to be honest. We're supposed to factorise 1601 and 1721 in our heads against the clock, are we?

Oh look! Here's another Rabbit Selecta 'suck the joy right out of it' classic.

I wasn't the one who put those lousy clues there in the first place.

I don't think they're too broad; actually, they're very specific - so specific that if you aren't familiar with the individual subjects you aren't going to get all the points for this grid. Which is how the game is played. This one was challenging for me but really well done.
