I actually just checked this out a few hours ago. Yep the Nextflix version has the original ending. Strange. On another note the print of the first Jaws on Netflix is not the BD print either. It looks to be an HD master of the print from the 2000 and 2005 DVDs. It also had the first surround mix done for Jaws in 2000 ie minus the restored sound FX from the original mono.
I feel like we should let more people know about theses especially the jaws the revenge one before Netflix rams a shark and blows it up for no reason lol
