I think this was a great movie for the family. I am actually a fan of the MCU (as you can tell from the photo) and I loved this movie. Of course, some cursing, but not too much. I think a mature eight year old can handle it. Some scary monsters, violence, etc. I even got jump scared! I'm going to be cliche and say that the main character, Billy, was my favorite. He's just so relatable. I won't spoil anything. There is a sad scene in this film where Billy finally finds his mother, who ends up not wanting him. He shrugs it off and leaves to go to his new family. This was a great movie and I hope you see it!
