I enjoyed the antics of Get Smart and felt that they did a very good job of modernizing it without losing the charm of the original show. And although they pulled a few gags from the TV series, they really didn't depend on it or over-do it. I give it a very strong A-, only losing a bit because it was still a bit goofy, yet quite enjoyable.
As for Kung Foo Panda, I went in with somewhat weak expectations because it looked so much like same-old-same-old. To some degree it was, but it was so well done that I really enjoyed it. But for the predictability factor, I'll give it a strong B+.
