Haha that's cool!

For me, it correctly guessed Inception from [hourglass clock], [a pair of wide open eyes], [zzzz]

Did anyone manage to make it guess Superbad?

I got all three.

Inception was slightly smiling face, the zZZ emoji, and upside down face.

Gladiator was Italian flag, classical building, swords

Superbad was clinking beer mugs, no one under 18 symbol, and ID button

Yeah, nerd face + cop + beer.

For Inception I got it on the first try with Zzz, Russian Nesting Doll and Business Suit
