I was not excited at all about the idea. I think the Care Packages interfered a little too much with the flow of the game (but, at least the Packages were planned and revealed in advance, unlike Pandora's Boxes).
But the casting made this season a winner. Multiple older people, strong women, and a great combo of misfits plus cool kids (which resulted in a great split of the house).
I hope the producers learn a lesson from casting this season and apply it to the summer season. Diversity (including and especially in age) works!
