I just finished re-watching Killing Them Softly for the first time since I saw it in theatres, and it's a movie I enjoyed both times.
However, one scene [SPOILERS AHEAD] that I particularly didn't like is the scene where Ray Liotta's character gets offed. It's the most weirdly over stylised death scene, with drawn-out slow-mo and questionable CGI bullets, glass and blood, juxtaposed with upbeat music in a way that just doesn't quite work (for me, at least).
It got me wondering what other scenes people don't like in movies that they otherwise enjoyed? It doesn't necessarily have to be similar to the one I described, just anything that took you out of the movie or made you cringe for a brief moment.
