Unlikable characters, mostly below average animation, terrible voice acting (for the most part), forgettable music, laughable dialogue, and an inconsistent tone are the reasons why I think Astro Boy 2009 is one of the worst animated movies I have ever seen in my opinion! You're better off watching Lilo and Stitch, Godzilla 1 & 2, Sonic 2020, Detective Pikachu, Sausage Party, Iron Giant, Godzilla vs Kong, Next Gen, Bumblebee 2018, Rampage 2018, Megamind, and Shrek Forever After over this insult to Tezuka's legacy.
