I definitely recommend this movie to anyone who has watched the last two films. This movie is definitely for you. There is a little bit of a violence issue since the main villain shoots spikes out of his hand and (in the beginning scene) hits several guards in the head. A little bit of blood seeps out, but that's only if you look carefully (like I did!). Aliens get shot and either get blown to smithereens (in a comedic sort of way) or turned into slime. There's a few parts where parents (and even kids) might get a bit grossed out, for example when Boris the Animal kisses a girl quite passionately while sticking his long, snake like tongue into her mouth. There's also a little bit of flirting between Agent K and Agent O, but very little. Another thing that might concern parents is the amount of swearing. And even though I don't remember hearing any F words, there are several uses of sh*t and bullsh*t, along with other mild exclamations. A conversation includes the word "darkies", but is not intended as an insult, only talk about a specific time. I suppose there's a message on loyalty and friendship, since Agent J goes back in time to save his friend and defeat the enemy, meaning putting his life in danger.
