The worst one and just shouldn't have been made.
I already thought there didn't need to be 5 movies for this story, 3 at max. The whole story line was dragged on and it was unnecessary. Now this final film, that almost seems irrelevant now, was so rushed that it didn't make sense. You were left with so many unanswered questions. The whole film was based off of Hardins POV, which actually had potential, but they definitely ruined it. Then Tessa comes in right at the end, everything is fine, Hardin proposes and then it shoots to a few years in their future and ends just like that. I don't think they knew what they wanted to do with this film at all. This final film basically ruins the whole franchise because it doesn't make much sense.
