Having only just seen the original trilogy this year, I’m treating film four as a direct sequel to the original.
The first is a classic but films two and three play up the humour to the point of ridiculousness. Part three is just cheap and terrible overall.
The trailers for BHC4 are pretty good so I’m remaining optimistic.
I didn’t even know they made a 3 and 4! When did that happen? The first two were great movies in their era.
