Why is it not a mockumentary?

I noticed, that this film diverts from the usual style of film making of the rest of the series and even the Countdown to liquor day. What is up with that? I much prefer the show when it seems like I'm watching COPS except from the criminal perspective. I think it was weird watching Trailer Park Boys that actually felt like I was watching a Professionaly done film with lots of cuts and nice shots rather than a couple camera guys with hand held cameras and the dick with the boom mike. I think Mike Clattenburg may have realized how awkward The Big Dirty was compared to the rest of the series and decided to do Countdown To Liquor day in true trailer park boys fashion. One thing I want to Add, I think this could have been a way better "happy" ending to the series even though I am very glad that they made more show after this film and another movie. I think the boys deserve a happy ending after all the *beep* they have gone through over the decade.
