Thoroughly enjoyable and very sweet.
I had a great time watching 'Jingle Jangle: A Christmas Journey'. It's very well acted, has a story that's entertaining and features neat special effects. The musical numbers are also good.
Forest Whitaker is excellent as Jeronicus, as is Justin Cornwell in the role of the lead character's younger self. Madalen Mills is impressive as Journey, while Keegan-Michael Key is terrific as Gustafson. Ricky Martin is a smart cast, also, as Don Juan Diego. It is a very competently cast film.
The plot is very good, I felt entertained and touched by it. It has a fair bit of humour, but also sturdiness and heart. That is all helped by the pleasant effects, which look nice throughout. There's also some nice use of stop-motion animation, too.
I highly recommend this.
