It's light. Funny. Easy to follow. Adventurous. Interesting.
The good guys save the African continent from a disease and the world's water supply from contamination. The bad guys get their due. The good guy gets the good girl and everyone lives happily ever after. P Cruz plays a strong beautiful Doctor. M McConnaughey is obviously attracted to her but it's not all about the conquest. She's no damsel-in-destress, although he does help her out of a jam.
No cursing. (EDIT to ADD: I should have said "almost no cursing". My "bad-word-meter" isn't particularly sensitive...I usually just notice excessive cursing or long strings of useless drabble.) No blatant s*x. Violence--there's shooting and a little fighting but no one gets hurt (like it should be in the movies) and it's not gore-ish or gross.
And did I mention Matthew McConnaughey? The man has great hair!
