The movie is loosely based on a Japanese-style comic strip and features superheroes that are all young scientists.
The new animated film comes from the folks who brought you "Wreck It Ralph" and "Tangled," based on an obscure comic book and set in a city that combines the best of San Francisco and Tokyo.
Baymax is the unlikely star of the movie and is designed to be a "personal health care companion," created by his boy companion Hiro.
Clint Silver, a real-life boy who watched the film in 3-D with entertainment reporter Sandy Kenyon, described the big bot as "a lot like a giant marshmellow, soft and sweet, and completely irresistable to people of all ages."
Together, they roam San Fransokyo accompanied by students at San Fransokyo Tech. Their target is a masked bad guy who mobilizes so-called micro-bots, but it isn't quite as scary as that may sound.
Any superpowers these kids may possess come from their brains, and upgrades come in the form of carbon fiber underwear.
If you are thinking it looks familiar, you're not imagining things. "Big Hero 6" started
life as a Marvel comic.
Silver, a 6th grader, wants other kids to know that this is "an ideal family movie" that he "recommends to all who want to laugh and have a good time this weekend."
The action is never too intense, and Baymax is so lovable that younger kids should also enjoy the 3-D adventure.
