It's probably best to not discuss the house party Marmaduke throws when the Winslows go away (complete with tired roof-jumping reference to "Almost Famous"), or the dog surfing competition set-piece.
And although the movie has been peppered with a few reasonably clever bits here and there - ie an amusing Almost Famous reference - Marmaduke primarily comes off as a bottom-of-the-barrel family film that's as devoid of positive attributes as one might've anticipated.
