I watched this movie for the incredible cast lined up, and yes the disfunctional family is fun. There are very fun moments that are also awkward.
But there are too many problems...
The giant tumor, the bad relationship with Ros and his ex wife, twins, the company going bankrupt, the dad suddenly working somewhere, the graphic novel that we don't fully seem to "see"
And then pouf...
She dies, the son returns to the family business, funeral and it ends with Becca going into labour.
There were so many things unresolved...
Maybe a several months later would've fixed a lot :)
