First things first: If you are new to the Point&Click-Adventure Genre, you should not start with this.
Ben and Dan are obviously two veterans of the genre and the games pretty much expect some basic knowledge from you.
I cannot call myself a veteran, but I made it through both games, but I have to admit, that some (or maybe some more) of the puzzles can be mindbendingly puzzling and/or irritating.
I kinda think that that should be part of a P&C, though.
The story itself is pretty hilarious and totally crazy. I think the humour is kinda British but I didn't really have trouble with it. I found the game very funny.
Unless you want this to be your first impression of Point & Click adventures, do get it!
