We visited the museum on a Sunday and so it was free entry. Apart from that there is not so much more to say that would make it worth a visit. If short on time or not able to visit the museum on a Sunday - don't prioritize it!
The building itself is beautiful but most of the exhibitions was on the other end of the scale. Several rooms only contained some TV-monitors displaying some kind of noise/distortion and literally crap.
A good thing besides the free entrance was that you're allowed to "touch and feel", something that kids could enjoy.
