Well I eventually decided to see Ghostbusters Afterlife, mainly because of the recommendations here.
It had a bit of a Goonies feel to it, and was basically OK until about 10 minutes to the end when it suddenly became overly sentimental, and everything started to feel a bit awkward. The sudden shift in tone was jarring to say the least.
I was also shocked at how old the original cast looked. I realise the first film was made 37 years ago (yikes!) but it doesn't really hit you until you see the original cast in their Ghostbusters costumes. That in turn made me feel old, and consequently I left the cinema on a bit of a downer.
