I only have the first season and the only thing that stinks is like said before, some have really shitty animation and the worst, to me, the Valkyries episode. I pointed it out to my wife, and then she was like “what the crap?” as one scene has TWO winstons in it.
I haven't seen the others seasons again, I don't know how they are. I want the next box to come out, but no info.
But on the main complaint, really the helicopter is hard to see? You know there are ultra lights you can buy and put together yourself yes? Plus IF this happened in real life where a group was so unique and indispensable as the Ghostusters, then laws would be bent to allow them to do things like run sirens and such.
