All that review says is
"I don't understand the science, therefore it's rubbish"

In case the reviewer (and you) missed the fucking massive tagline in the comic, it's a maths and science comic. Not understanding it doesn't make it not funny full stop, just not funny to you.

And since that review basically says "anyone who understands science or maths has Aspergers' " then you'll forgive me for suggesting that there isn't really any need to counterpoint an opinion that fuckwitted that it might as well have been written by a 5 year old.
