I was watching this movie again the other night and it made me wonder, "What kind of intertype relation is going on here between Joel (Jim Carrey) and Clementine (Kate Winslet)"?
I'm tempted to say that Joel could possibly be INFj. He struck me as being Se-averse at the least, if not PoLR, and Clementine seemed to very naturally give off an Se vibe, possibly leading. She appears to demand some Fe from him when he comes off as being more Fi than Fe.
Do you suppose that this might be an example of a relationship between conflictors? Well, I don't know, there definitely seems to be a tangible tension between the two of them which may or may not be so simple as a personality conflict. It's hard to say because they seem ill-fated for one another, yet there is also a unique sort of attraction between the two that almost looks like it springs from how vastly opposite the two of them are, though this also comes through in the way their relationship deteriorates.
