The direction is just plain bad. A tier actors delivering dialog like a school play for part of the film.
The writing would be boring if it weren't for the cringe and akward moments. The girls are a little too old to All still be living with their mother save one graduating HS at 15 (isn't that worth a bit of exploration)?
Chemistry is meh with major stars, so the uneven performances are firmly on the sholders of the Director.
Just..... blah. Amazing to say with all this talent.... seriously WTF?
Writing is boring and just off (if its supposed to be funny) direction bad, Great cast wasted.
