It's an enjoyable movie, it leans more towards Damian's story hence why it's titled "son of batman". Most batman fans would be disappointed that Damian is able to defeat Slade, nightwing and batman (even if bruce was going easy on him) as they all have more than a decade more of experience than him. Even the fight with ubu was pretty jarring plus how he is able to do all sorts of other rather ridiculous feats.
