Hrmn...I don't watch a lot of cinema, but I'll give this a go:
2010: Toy Story 3
2011: X-Men: First Class
2012: Wreck-It Ralph
2013: Monsters University
2014: When Marnie Was There
2015: The Boy and the Beast
2016: Deadpool
2017: Thor: Ragnarok
2018: Spider-Man: Into the Spider-Verse
2019: Aladdin...god help me. That's how bad 2019 has been for cinema.
I guess my choices are pretty uninspired, but as I said, I don't watch many movies. 2010 was the only year I struggled to pick a favourite. For someone who prefers Renaissance Disney and is fed up with superhero films that butcher great comic book storylines it's depressing to see how many CGI and Marvel movies made it onto my list too...although Into The Spider-Verse was well-presented, which made up for it retelling Miles Morales' origin story with the more popular Spiderverse characters thrown in to make it more interesting. Although I'm still annoyed Superior Spiderman and Spider-UK didn't make it in.
