The usual, nothing innovative about it!
Everything I wrote was just my personal opinion, definitely not intended to offend anybody. This should have been one of the best comedies of the year, but now it belongs to one of the worst. I recommend 'Grandma' instead this which I felt a much better comedy.
At this age, Robert De Niro was unbelievably awesome, though his character needed a good support from another and that's where as usual Zac failed to deliver his part. I would have preferred someone like Taylor Lautner who's desperate for a breakthrough than the Zac who ruins always.
The screenplay was from the 'blacklist', knowing this they should have been more careful while casting for it. The story was okay, because it was not meant for one of the greatest films of all time. It was sort of a weekend getaway or the bachelor party theme, but the film gives its original reason and then those developed plots were too familiar if you have seen plenty of teen films, in the party theme.
It's supposed to make us laugh, but there are lots of outdated humours tried in the unusual route to narrate them. The grandfather-grandson combo was an excellent idea, the main plot revolves around them and it should have remained that way, but the undetermined romance was an interruption. Or they should have developed a decent romance track for a better balance in the genre.
At least it would have been all right if it was a teen film. Many of those who appeared in it were actually too old to represent the roles given to them. That's fine too, because films are fake, everything is make-up and performance, but none were at their best except De Niro and Aubrey Plaza. It is definitely a film to skip, that's my opinion, but they're a few who are defending it, so be careful that I'm not always right and they're not always wrong if you want to choose it.
