Lego movie and lego batman, star wars etc
"It'll be interesting to see how Playmobil: Robbers, Thieves & Rebels measures up to 2014's The Lego Movie, which enjoyed huge public and critical acclaim, but inexplicably and controversially failed to get nominated for the Best Animated Feature Oscar"
As was shown in many award ceremonies, it's voted for by the overpaid members with backhanders from studio's
None of them would vote a movie with no mega million pound stars voices in it.
Personally they appeal to all ages which makes them so popular, imagine if Gravity had been so popular how much it would have made (even without overpaid stars fees)
