Actually really ok, but there are also shortcoming...

Actually really ok, but there are also shortcomings that the city of Heidelberg does not seem to be entirely innocent of, as it seems to exert enormous structural and temporal pressure on the operator, who could probably let the whole project fail financially, although that Cinema is now at least partially open.

The cinema halls are very tastefully decorated, but there is no such thing in the lobby. Relatively cold and concrete-like ambience.
Unfortunately, the Atmossound is extremely restrained in its capabilities, but this is generally due to Dolby and the mixing of the films.

But what honestly does not work (especially not for families) are the horrendous prices.
I feel sick even as a high earner.
10% advance booking fee of the total price, what for? But that the operator has planning security and needs fewer staff thanks to online bookings?
Then all the additional prices for every invented little thing to make the ticket even more expensive. Honestly, make the effort and download the price list as a PDF from the site. You fall down! You can even add 2.50 as you like, depending on the film, in addition to a number of other surcharges.
No, it can be real that the operator is in financial problems (I can understand, given the circumstances) but he won't get out if nobody goes into his palace, because it's just too expensive. 60 as a family with 2 children is simply way too much to watch a movie once.
Then it's better to collect less and get the house full, because that's zero. Apart from that, nobody needs a gondola lift, which is not opened, in a cinema and 8 parking fee for 2 hours of film, which I am supposed to pay at the machine in the dark (light does not work) either.

However, I still go there sometimes so as not to break the last HD cinema, even though it has just been rebuilt. But not as often as I would go if it were cheaper.

By the way: finally turn on the light in the pool for the poor fish, they are not cave animals!

So, take criticism to heart and implement it, then something will happen
The potential is there.
