THEME: phrases contain BAD
GOOD ONES: Big intro? MEGA
One with growing concerns? GARDENER
BTW: Vince Gilligan TV drama {& theme} BREAKING BAD [The clue suggests the word BAD is being broken, but in fact the word is whole; so it appears we must interpret "breaking" as "bursting upon the scene."]
Movie lioness ELSA [as I read the book first, I see it has a "literary lioness"]
Normally Dr. Sessa gives us at least one scientific entry and an Italianate one, but not this time --- okay, maybe TONSILS.
RATING:

Three grins = Loved it; Two grins = Enjoyed it; One grin = A bit bland for my taste; One teardrop = Not much fun
