I agree it was pretty fun and also could have been improved with more dong
But yeah some scenes were done pretty well, the cyclops was actually pretty unnerving and the bone cracking and body horror during the pig scene did make me flinch a couple of times.
Unfortunately the other cinema goers weren't hype like yours, I just had one guy with the flu behind us loudly sniffing every five seconds. Poor guy, I hope I don't get what he had.
LET'S GOO" whenever they blinded the poor cyclops and was angry as hell at Telemachus (he literally shouted 'DO SOMETHING' during the contest fight) & as a result my experience was heightened.
