I expected this to be a Vin Diesel version of Kindergarten Cop, and I was largely correct.  However this movie was very slow and tedious building up to the good stuff.  The big Navy Seal changing diapers and coping with teenagers sneaking around and throwing parties is all pretty standard fare and predictable.  the director just long-winded the build up quite a bit.

Once the ninjas broke in the first time the movie just almost jerked to life.  Kind of like trying to start your car, and it just didn't quite hit.  Soon after that the movie came together for the last 45 minutes or so.

The last parts make everything else worth the wait.  Very enjoyable.  The movie is worth the rent (or the buy), but if you want to go "Yadda Yadda Yadda" as you skip forward to chapter 9 on the DVD.  That's where the oldest son, Seth, quits the wrestling team that his father wanted him to do, and joins the cast of The Sound of Music.  It gets interesting there.
