This series really has its ups and downs despite the high ratings. They really went overboard with the product placement scenes for Coke, Jiff peanut butter, Eggo, etc. Which I found very annoying, especially when it happens during serious scenes because it makes it seem foolish. There are some great action scenes though and the special effects are interesting and well done. The young actors do quite a good job overall and they deserve credit for making this series a hit! I just finished season 4 and the only season I really didn't like was season 3 but it's enjoyable overall and worth watching!
