(Un)fortunately, I'm not one of them. I only bought the hot dog stand for my circus diorama and because I lost the original version (3848) during my childhood...
Ghostbusters mean nothing to me... it was sort of lame even back then, now... interest = 0
Though we did get the car (it IS different from everything else) and a couple more smallish sets - AND the best part - those pups

.. a few times. By far the best of all the ghostbusters theme - AND a small set

AND with a beautiful woman..
Also, the klickys are.. BROWN, so...

But 50 is far too much for those - I didn't expect it to be sooo expensive. Wasn't on my list anyway - though if it was a nicer klicky, I'd like one or two..
Same goes for How to train your Dragon 1 🐉 from 2010
The first sets from HTTYD are based on the second movie... I think.
