(Hello I'm now in my 20s and laugh frequently about the title and amount of films on this list ahahahaha, please use my updated lists instead thank you).
You'll be able to tell which movies I watched when I was 10 years old and which movies I've watched since I developed actual taste.
I have a copy of this list saved so expect an updated version at some point once I've watched/remembered more. As you can probably tell by the small size of this list and the range of quality, I have a very long list to catch up on.
