The great thing about this is: the gang’s all here. With added baby for extra flavour. Five years on from saving NYC the Ghostbusters are in disgrace. Venkmann (Bill Murray) has a shonky psychic cable show while Stantz (Dan Aykroyd) and Zeddemore (Ernie Hudson) are terrible kids’ entertainers and Spengler(Harold Ramis) has a real job in a lab. Dana Barrett (Sigourney Weaver) calls upon them when her kid (from the man she divorced after turning down Murray) displays some haunting behaviour. Add a supernatural sea of sludge sailing through the sewers – an existential despair on the part of city dwellers? – and a very driven diabolist (Peter MacNicol) keen to adopt said baby to channel the demonic Vigo of Carpathia and we have a paranormal debacle. It’s not great and some of the writing is lazy but the players all give it their best in this riff on the original. It’s zany, funny stuff and the baby’s great. Directed again by Ivan Reitman, with supersized slime.
