Strong, clear message that working as a team with people you care about and respect is better than trying to do everything yourself/alone. Thinking you're better than everyone else is bound to backfire (i.e. humility is important). Trying to avoid pain by refusing to make connections with others only hurts you more in the end.
Positive Role Models & Representations
Some use of insult/potty words, including "butt," "stupid," "loser," "sucks," "farts," "shut up," etc. Also phrases like "dear gosh," "holy cow," "what the heck," and "oh em gosh," plus occasional British slang such as "ruddy." Some jokes are made about Dick/Robin's name.
Most of the characters have tie-ins to movie, comic, and book merchandise/franchises (including DC superheroes, Harry Potter, The Matrix, The Wizard of Oz, Lord of the Rings, and many more). Also appearances of/verbal references to brands/products including Vitamin Water, Google, iPhone, Bed Bath and Beyond, and romantic comedies like Serendipity and Jerry Maguire.
Ease of Play
Reference to Alfred drinking wine. Beverages at gatherings, but not clear what they are.
