Actually it's OK, at least we know how OLAF knows his name and why he likes summer so much. This is the special, only 7mins or so, so I can live with that, but I still don't think it's very as good as Frozen I.

Similar graphics to Shrek and other high quality cartoons. Also environment is magical, relaxing, video game like or dream like. Reminds me of Croc video game. Bit unclear speech and could not find subtitles. Unfinished story or unclear, without purpose. I expected some end, but no end, no that summer. This is good because not time waster, simple, and based on book or story. Efficient to watch for all IMDb medal collectors.
