Do the ticket kiosk works?

Yes they work, you can also use your phone and go directly to the entrance.

No, there is always a problem!!!

Some of them work most of the time, but there's usually at least a couple of them down at any given time (you can only browse showtimes, but can't buy tickets). One of the machines is also obnoxiously loud, with the "beeps" when you tap the onscreen buttons being far louder than the other machines.

Yes rather nicely too

Yes, they do. But I still see some people line up to actually talk to someone, maybe they don't like to communicate with 'something' when I visit last month.

Yes. Plus, they're more efficient...

Yes
