I can see that... For a lot of people they wouldn't know the original Shaft with Richard Roundtree where it all started, so for them it might be their first outing. It never tries to take itself seriously and for me personally it's an enjoyable flashback, I suppose in some quarters it might seem out of place with his old school style and views but that is part of the fun clashing with his son on various subjects especially women and how to handle them and with Samuel L Jackson as the current Shaft it made it very watchable for me.. I enjoy his screen presence.. It may well not be your cup of tea but I am pretty sure you will know within the first 30 minutes..
