I went to the theatre with a friend.
So tell me, please, why does none of the builders-designers (and all the other involved) theaters, cinemas come to the mind to put the seats not dumb one after the other, when people all the session / spectacle glimps in the back of the head in front of the sitting, and shift the rows in half-seats to the side in relation to each other? Like bricks in a brick, each layer of bricks is moved by half the brick. Then the scene will be remarkably visible from anywhere, the back of the head sitting across a row from you - it doesn't bother, you won't have to slide around the place, bending to the sides, looking like what's happening there on the stage. It will be comfortable!

Why no one? There are such theatres. But the width of the passages in the hall according to the requirements of fire safety may not be less than the minimum allowed. For example, in a small hall with three passes towards the stage, the number of seats is reduced by 2 in each second row. Not every theater can afford such a luxury.
