Finally saw this movie last night and loved it. Had a few giggles in there for jus t my sense of humour (big kid). It also gets you in the feels and makes you think of being a kid, and to never let go of your imagination and inner child. ( Which I never have even at 33 lol)
I also personally took from it that he is trying to touch on mental health and to show kids it's ok to embrace your emotions and that if you have your imagination you are never alone.
Man it really got me I really loved it. Great for the kids but also for adults and kids at heart.
