Film: 'Why Him?"

Now back in business following prolonged absence. I wish to express my gratitude once more to those of you enquiring after my welfare during my indisposition. Am 95% recovered now, thank you.

My final film of the year, like 2016 itself (largely), is a stinker. Spectacularly unfunny, gross-out 'comedy' which only drew me because of the presence of James Franco - someone who, I'm quite aware, is a great turn-off for a lot of people but for some curious reason I continue to find fascinating.  
He plays a heavily tattooed, brash and potty-motormouthed billionaire with huge gadget- and computer-driven home complete with nerdy staff and an unfunny, slightly campy bodyguard character who tries to keep Franco alert by subjecting him to surprise combat attacks, as was meted out to Inspector Clouseau in the 'Pink Panther' films which, incidentally, had also left me unsmiling. 
Franco is dating the daughter (Zoey Deutch) of parents Bryan Cranston and Megan Mullally - whom I've not seen since 'Will and Grace' and would not have recognised her if I'd not known. 
The Franco persona invites the family (including a 15-year old son), the members of which he's not yet met, to spend a few days at his home - an entirely 'paperless' environment, so it's hardly a surprise that there's an extended 'jokey' toilet section. (Ha ha ha! Laugh? I did not!)
Franco's language is liberally peppered with coarseness in words and expressions, much to the horror and disapproval of both parents - though once the mother takes a sample of 'grass' her personality alters and she gets all flirty. Cranston, as the father. is adamantly opposed to his daughter's choice, notwithstanding the fact that Franco is on the verge of actually proposing, and making his new wife a President in his company. 
All so drearily unimaginative. To make matters still worse, the whole boring business is wrapped up in the final scenes by Cranston giving sage, homely, paternal advice to his daughter and her intended. Oh, PLEEEZE!

Director and co-story- and screenplay writer, John Hamburg, who was involved in 'Meet the Parents/Fockers' and both 'Zoolanders' has hardly stretched himself with this material. It's one of those films that I think will only appeal to those who have a very limited acquaintance with such 'comedies' to date - very much a 1970-80s thing, I think, with the formula practically unchanged, only the language assuming that the cruder it gets (including here an explanation of 'bukkake') ergo it must be funner. Wrong!..............2.
