My pick would be The Lion King. Its animation is beautiful and very detailed, and the backgrounds look detailed. The voice actors do a great job in both Finnish and English, and the characters themselves are memorable and interesting. The story itself has combined aspects from many stories and made the mix work very well, and the use of nice songs and beautiful yet haunting score help to transcend the experience into a new level.
Although there are other great Disney movies out there, The Lion King has always stood out because of its fine mix of different elements that Disney is known for.
