Robert Downey Jr. absolutely nailed it as 'John Dolittle', being an MCU fan I never knew this side of RDJ as an actor. It's so good to see the beautiful bond between the animals and Mr.Dolittle in this movie, the character of Stubbins is also very well written. After watching the movie, I just had a feeling of how beautiful the world would be had we all had such kindness, compassion within us towards the animals in real life.
It's a beautiful movie with a lovely message and you'll never realize how quickly the time passes. This movie is one such example where you realize that reviews aren't always reliable.
