I was hooked in the first 10 minutes. Not only is the animation beautiful and the color pallet very bright and pleasing, but the character design for Sherman is absolutely adorable. Not only that, but Ty Burrell is an absolute delight, and the story is actually very compelling and witty for a children's movie.
I am also a huge fan of historical anything in films, so I really liked that while yes fictional and intended to be comical, the history they brought in with the time travel aspect was really interesting to watch, and brings a little humor and goofiness to some very famous points in history. The script is intelligent, cute, and able to bring two generations together to enjoy one movie.
