I saw TPM in theaters when I was 3 years old too but barely remember anything except for one scene. Pretty random, but it’s when Jar Jar, Qui-Gon, and Obi-Wan resurface in their water pod thing.
I don’t even have much recollection of me liking it or disliking it. I do distinctly recall having the VHS of it a year later, and felt ‘meh’ about it.
Funnily enough, I enjoyed AotC the most seeing Yoda flip around like that.
TFA experience wins by far though. All other times, it was just me and my dad since my brothers were either too young to go to a theater or not even born yet. This time, my dad AND my little brothers could all enjoy it!
