Common Sense Note
Parents need to know that although there's very little in the way of language, sex, and violence in this well-acted family drama, it does deal with some serious themes -- including death (of both humans and pets) and abandonment -- that are on the heavy side for young viewers, who may need guidance understanding what they see. Parents are shown discussing their frustrations with their kids and yelling at them, and kids are shown cruelly teasing a main character and calling him "weird." Some social drinking, but only among adults.
Sexual
Content
An awkward-but-sweet kiss.
Violence
A father and son throw plates around, but not out of anger. The father also loses his temper, though he quickly regains control of it.
Language
No swearing, but some insults ("weird," "stupid," etc).
Social
Behavior
A man reaches out to a young boy on the fringes of society. The child has been abandoned and has chosen to portray himself as different, which only alienates others. But his adopted dad persists, and, in turn, heals from his own tragedy. His family is pretty supportive, too.
Consumerism
Some products, such as sunblock and sunglasses, are noted, but in general there's no egregious label-pushing (though Dennis certainly does like his Lucky Charms...).
Drugs / Tobacco /
Alcohol
Some drinking (by adults) in social situations.
