Make quality work and people will watch it because it is good. Throw junk in there, and you end up with junk coming out because you wanted per-adolescent kids to giggle.
But there have been some very good movies that managed to pull off the lowbrow humour and do it well.
Take a look at Despicable Me (the first one only) and that was a very good movie that could appeal to every level of audience and the lowbrow humour was so well written into the storyline that it added to the plot and story movement to make it integral. Not just stuck in there for giggles but added no story purpose.
On the side of the Hobbit. It should never have been a trilogy to begin with. They could have done it as a rather long single movie and it would have been entertaining. But GREED got in the way so they added scenes that were never in the book. Added story lines that were never in the book. Dragged it out to make it into 3 parts and all of them are rather long movies parts. It took the Lord Of The Rings idea and tried to copy it forgetting that LOTR was in itself a 3 book trilogy and tried to do the same with a single book. Failing quite badly at it. But it does have some merits and entertainment value. Much better at home with a good supply of beer and corn chips. I am told it's wonderful on illicit drugs but i am not into that sort of thing.
