A couple of weeks ago, a few of my friends and I went to see the Lego Movie 2 in theaters. Almost as soon as the movie started, a row or two in front of me a young child, maybe 3 years old judging by his voice, began screaming. His Parents shushed him and calmed him down, which was a relief.

About 5 minutes later he started screaming again. Same thing, his parents calmed him down again.

This repeats over and over, every few minutes throughout the movie. Each time I get angrier, but I keep it together. I look to my friend next to me each time this happens, and see that he is annoyed as well.

About two thirds of the way through the movie the kid starts screaming again and I can't take it anymore.

I yell "YOU'RE RUINING THE MOVIE" in hopes that one of the parents would finally remove the child from the theater.

This was the first and only time I have yelled at anyone in a movie theater. In the past, any time I experienced a noisy child in a movie theater, their parents were quick to take them outside to keep them from ruining everyone else's enjoyment. 

During the rest of the movie, they try to quiet their kid down by playing a movie on their phone at FULL BRIGHTNESS AND FULL VOLUME. To be fair, it did keep the kid quiet. But it still completely ruined the experience for me.

As soon as the movie ended and we began to leave, the mother glared at my friends and I (I assume she didn't know which of us yelled at her). 

Outside the theater, my friends are all mad at me. They say that the kid was a minor inconvenience but not a big deal, and my visceral reaction ruined the end of the movie for them.

I get that it's a kids' movie, but I still don't think it's acceptable to ruin the movie for everyone else because you don't want to take your kid outside. Everyone else payed $14+ for the movie and it seems really self centered and rude to think that your kid being in the movie theater is more important than other people's enjoyment.

I know I didn't handle it in the most mature or effective way, but I still believe that I was justified in yelling at them. Am I the asshole?
