To me, it's a film that they finally got right.
While I like the original 1966 animated film, I felt like the tone of the film was charming, nostalgic, but not wanting to be happy or have fun. I like it, but it's not my favorite and the movie itself is kind of showing that it has potential, but isn't that welcoming to the audience.
I hate the 2000 live action film. It's creepy, ugly, and vulgar yet got a PG rating. It felt like a horror film instead of a family Christmas film. Also, I didn't like the acting along with the tone.
This film is charming, but it is also fun. I love it for adding good humor, enjoyable characters that have development, a happy town called Whoville, and the Grinch who is enjoyable.
