...I just got back from the UK premiere of this in the IMAX and it is really, really good. Lots of laughs from the audience, some fantastic motion graphics as explainers (look for an excellent riff on the original NES game!) and some very sweet reminiscence from all sorts of folks. Worth the wait for me, and nice to see a bunch of names I recognise up against my own in the Kickstarter credits.
So yeah, definitely the definitive Ghostbusters doc, and I spoke to Claire Bueno and the GB2 one is in post now so is also still coming!
