I'd try the first Transformer movie on them first, to see if they like it before attempting the second one. (It's on DVD.)
I thought the original movie was very much over-the-top with non-stop action, and a thrill a minute -- but this sequel is more of the same only amped up far, far above it, thus it doesn't really give you a chance to catch your breath for the entire 2 1/2 hours.
The big caveat to me is that some things were added to the latest movie that detract from it being entirely appropriate for all audiences, if you know what i mean. There's a lot of off-color, extremely sophomoric humor that doesn't really add to the story. And there's more than a few "choice" words that caused me to wince for the sake of my two little pairs of ears sitting next to me. Thankfully a lot of the innuendo goes above the heads of my two, but I wish most of that would have been left on the cutting room floor.
Other than those quibbles, I found the movie very entertaining. Very Hollywood. Very Big-budget extravaganza.
It's good to hear that H helped out. I'm sure your S3 really enjoyed having some one-on-one time with his father. They need that so very much.
"Dukes of Hazard", huh? I never really caught too many episodes of that series -- I guess i was busy watching other shows, like the original "Battlestar Galactica", in those days.
