Do you still watch the sequels of a bad sequel?
For example,
The first Pirates of the Carribean was a good movie, so predictably when Pirates 2 came out you'd want to watch it. Turned out it was bad, or at least underwhelming, so when Pirates 3 and 4 came out do you still want to watch them?
Personally, I never watched Pirates 3 & 4 after I saw 2. I also never watched Star Wars Ep.2 and 3 because of 1. However, I went to see Rogue One in cinema after I rented The Force Awaken on dvd.
