All right, I managed to watch this 22-minute-short (or featurette as this would have been called by Disney if this had been shown during the '70s) before the feature Coco before the studio pulls it after tomorrow because of numerous complaints of patrons thinking they went to the wrong theatre because of the length. Many reviews on this site are negative because of what I just cited so I kept that in mind as I was watching it. My verdict: Yes, it's a bit long for a short and the songs seemed to be a bit too many. Still, it's quite entertaining during much of the running time, there were some funny gags, and a pretty touching message about family in it. Olaf did not wear out his welcome as I partially feared and the fact that the others like him enough was enough for me to like him, too. In summary, Olaf's Frozen Adventure was entertaining enough for me.
