Yes I think some of not all of the special f/X have held up well in ghostbusters . The acting doesn't even need to be questioned . The stay puff still looks great to me and the spectres also . The only thing I can recall looking a tad rubbery is the vince clawthorpe dog /beast Lewis thing with red eyes ; the gate keeper animal form . Only a tad though
