I thought that you're being a little too critical. Others should know that Norway is a country with relatively high costs of living.
The minimum wage for a cleaner is 46k per year ($23\h). And your boss better not try any shenanigans, because you're most likely unionized and shouldn't really be messed with.
I've found $18 ticket for opening week for Hail Mary in my city. Most of them were at $23, but that's for the premium sall, with shaking seats or other fancy stuff.
So a person with a job looked down upon in most other countries can still get one ticket for an hour of work.
Reason I've felt compelled to reply was because cinema tickets always felt cheap to me in Norway, compared to more like 2h of work for minimum wage worker in Poland where I originally come from. Compared to any other prices like $15 for a beer at a bar or $30+ for a bottle of vodka in the alcohol shop* they just always felt like a steal. YMMV OFC.
*Interesting trivia: The alcohol shop is called Vinmonopolet and it really is a monopoly. The only company allowed to sell alcohol above 4.7% is run by the state. They have shops in towns, and if you live far from one (like most of northern Norway past the polar circle) you're most likely getting your alcohol from homebrew mafia instead.
I wasn't trying to be critical actually, as for non-opening weeks I agree, it's not bad at all. I mainly just wanted to provide a point of comparison.
IMAX opening week is a bit more but are comparable to mid-range concert tickets. And it really is a big screen, so can definitely be worth it.
The snacks and drinks at the cinema is wild though I think. As a comparison the M's they sell are twice the price and half the size of that from the grocery store. I get that they want to make some money on it, but 4x the price is just too much for me.
