For the whole family: Wall-E. Both DS3 and DS9 and DH42 loved it.
DH and I also enjoyed watching Memento recently. The main character wakes up and realizes he has no recent memories. The story is very fractured -- but intentionally so --- and very well-crafted. I think it got an Oscar for editing.
Bonus for Grinity/Trinity -- stars Carrie Ann Moss, whom I always pictured when I saw Grinity's old screen name -- so I imagined her looking cool, leaping through windows, evading agents, as she advised wisely and supported admirably!
