Does the ending of Casablanca lack emotional impact because they don't suck face?
Plus as I said, they could establish the finger touch as a sign of affection earlier in the movie. Plus, while I would prefer the finger touch, it's the fact that the scene goes on for as long as it does that is my main issue.
The scene is 28 seconds long, and they're not "sucking face", they're kissing. If you don't care about the difference, you may belong to one of the minorities that I talked about earlier.
