Watching movies and animations are not forbidden (Haram) in Islam if they don’t contain any prohibited elements. Muslims are allowed to watch, enjoy, and learn from movies that contain no indecencies and has no harm for any individual or society. 

However, being a Muslim means that one has the aim of improving to the highest levels of faith. Thus, one should keep in mind the verse of the Quran that says: “The life of the world is nothing but play and diversion, and the abode of the Hereafter is surely better for those who are Godwary. Do you not exercise your reason?” (6: 32)

Therefore, even if the movies and animation are lawful (halal) to watch, we should make sure not to waste our time watching too much of them and neglect our main tasks in life. 
“… and eat and drink, but do not waste; indeed, He does not like the wasteful.” (7: 31)
