well the closure for the series is supposed to be in DMC itself..they said that without 3 they would be happy with where DMC end because it got the right messages across and the emotional development of Will, Liz and Jack makes a pretty bold statement.
and it does suggest that Jack wants Elizabeth, Elizabeth realises she's just lost the good man she might love and it reveals a part of herself she cant live with and all she wants is to bring that good man back into the world, into HER world..Will seems to spot this and lets her do it.(we have to imagine we know nothing of AWE) she probably cant live with herself because used Jack's good nature against him(one to many times)....and the good side is the part she most loves about him...if anything
which would explain why she finds it easy to distance herself from Jack in AWE because Jack is behaving cold and is not being good in the draft script
Its the very reason she killed him in DMC..because if the good man isn't there (the one who just came back for her) it makes it easier for her to be with Will...but then she realises just how much she needs Jack the good man back in her life..because she loves that good man...this final choice in DMC is AFTER a rather bold statement that she chooses will in DMC..
Also Terry said the ending to a movie should be a solution to a problem raised earlier in the movie, it should be unexpected yet make sense to what we've sen..and yes the proble, was raised early in the movie by Elizabeth herself.
"if it weren't for these bars I'd have you already"
The bars are there because of Jack..if Jack was not rescued in movie 1 and was left to die Will/Liz would be happy together and married by now..in the end she thinks that without Jack there all her problems would be gone..and its not just problems like her and Will not being able to get married and trusting Jack..ts the fact she's attracted to him and the good man just came back for her and IMO her feelings for him escalated..if Jack's not there it makes it easier to be with Will in her mind..oh how wrong she was..she has the whelp with her at the end..and nope..its not the right thing for her. She wants Jack...that is her final choice
