A key message is that it's wrong to consider all Transformers evil -- i.e. you shouldn't discriminate against the whole because of the violent actions of a few. Shows the power of belief/faith/legends and the importance of unconditional friendship. Unfortunately, the positive themes are frequently overwhelmed by the fact that violence is used to settle all conflicts, as well as some stereotyping.

Tons of loud sci-fi/action violence -- including explosions, weapons, battle sequences, and fights between Transformers, humans, and Transformers and humans. Some people (especially in the Dark Ages flashbacks) and Transformers die. There's an upsetting fight between "Nemesis" Prime and Bumblee in which it seems like Prime is going to kill his loyal friend.

One passionate kiss. Hand holding. Innuendo about how Vivian is dressed like a stripper. Jokes about Cade's "chaste" lifestyle. A shot of Cade shirtless with the talisman slithering down his body into his pants. In one scene, Vivian's mom and aunts think she's having sex with Cade because they're in a room making a lot of noise and saying things like "I can't get it out," etc.

Frequent use of "s--t," "ass," "a--hole," "bitch," "d--khead," "damn," "pissed," "stupid," "jerk," "horses--t," "Christ!," "God!" (as exclamations), "mo-fo," etc.

The entire franchise is based on Hasbro toys, which are popular with and marketed to kids who aren't old enough to see the movies. Also many product placements within the movie, from General Motors cars (Chevrolet, Dodge, Cadillac, etc.) to imported cars (Lamborghini, Range Rover, Mercedes, Lexus) and apparel (Nike, Adidas), as well as products/logos from Beats and Motorola.

Adults drink both in flashbacks and in contemporary scenes. Merlin is described as a drunkard and drinks from a bottle; he later promises to give up drinking if a Transformer will help save humanity. King Arthur and his knights lift up drinks for a toast. A Transformer brings Cade a beer from a fridge full of them. Women drink during a get together.
