Adam Sandler is just too shrewd isn't he: his movie "Click", heralded as a touching message movie sold as comedy, is nothing more than "Ebaneezer Scrooge" and "It's a Wonderful Life" thrown together. I guarantee that' how it was pitched in Hollywood.
Yes, you are right about "Nothing new under the sun",a line I think from the Bible. But there is a fine line between clever and stupid, or rather between 'homage" and "shamelessly derivative". Click is the latter.
I haven't seen it but I heard it was basically what your point of view states along with some unnecessary male nudity. And all the bad feedback I heard about it was enought o deter em from going to see it anyway.
