My family and I enjoyed the movie. It was full of action and silly jokes. Don't believe what the "real reviewers" say. It may not be an Oscar winner, but it was a winner with my kids and I.
The kids enjoyed it. I though it was funny. It was one of those movies an adult can sit through and not count the minutes until it ends. The penguins are hilarious.
My entire family, ages 42, 22, 11, 10, 7 and 5 loved this movie. I saw the first Indie movie in the 80's and my kids have watched our DVD's. You got the inside jokes if you've seen previous installations, but if you hadn't watched the other 3 movies you would still enjoy this one. It was just what you would expect, crazy stunts, lots of action and best of all Harrison Ford.
