Feel good movies

A few years back my partner said she would take me to a "feel good" movie ... which turned out to be Slumdog Millionaire. I was quite distressed with the mother being bashed, children being mutilated so they would be more "successful" when they were sent out begging - and just generally. I remember asking her (yes, through what might have been tears) when it was going to start being a "feel good" movie - because it didn't seem like that at all. Today, we were at another movie, a Rom-Com, and it certainly was that but there was a point when one of the characters is having a tender moment with another and as he was about to whisper sweet nothings to her, he gets shot. It truly was unexpected and, I think probably a wee bit violent for what it was. Up until that point in the movie, there had been violence but I don't think anyone had been seriously injured. Have we as a society become too used to violence generally - so that we aren't bothered when someone is seen to be violently attacked and hurt in a movie, and how do we then interpret violence when we see it in real life? It's an age-old question of course - does violence beget violence - or at least the acceptance of it?
