Well, it's hard to say for sure. You'd have to look into the background and the creator's statements to determine if it's based on actual events. Sometimes what seems like a true story could have a lot of creative liberties taken.
El Deafo is indeed a true story. The author drew inspiration from her own childhood and experiences with hearing loss to create the narrative. It offers an authentic and heartfelt account.
Not necessarily. 'El cantante' could draw inspiration from real-life, but it's probably embellished or fictionalized to make for a more engaging story. There might be some truth at its core, but it's not a straightforward account of actual events.
I'm not sure specifically what the 'el momo story' is about as it could be a very unique or regional story. It might be a folktale from a particular culture that involves a character named Momo.
Sure. 'El Chapo' is based on the true story of the notorious drug trafficker. It attempts to depict his rise and fall, but keep in mind that some artistic liberties might have been taken to make it more engaging for viewers.
