I really enjoyed all the Shrek movies as an adult (my kids loved them as well) and we talked about it on the way home and we thought the final Shrek was the 2nd best Shrek ever behind the original. We highly recommend going to see the final installment. Eddie Murphy (AKA Donkey) is hilarious.
I love movies that keep you wanting more and more, I was hoping the movie didn't end. I also love movies that make you feel good (sometimes in the form of crying) and this movie did that just as THE ROOKIE did when people never give up in their dream and the fact they still have great people in this world who don't care about race or what others think if it is the right thing to do.
