Im watching Enders Game (Underrated flick) right now and this kid Asa Butterfield deserves to be Spider-Man lol kids acting is off the charts for his age and is believable. I literally had moments I pictured him in the spidey suit with his mask off. They just need to get his humor game right and he will be probably the best peter parker.
I not only found Ender's Game to be pretty bad but for Asa's performance to be boring, stale, and forgettable.
To be fair, you did say The Last Airbender was an 8.5/10 for you.
