In this third film in the Diary of a Wimpy Kid series, Greg Heffley (Zachary Gordon) wants to spend the summer before eighth grade playing video games and maybe, if he can finagle it, getting closer to his crush Holly Hills (Peyton List). The former plan goes out the window when his dad Frank (Steve Zahn) decides to ban video games from the house. In order to connect with his young son, Frank schedules a number of fishing trips and signs the boy up for Scouts. Greg has more luck on the girlfriend front when his best friend Rowley (Robert Capron) invites him to go to his family's country club, where Holly works as a tennis instructor. Soon, in order to avoid spending so much time with his dad, Greg lies to his parents and says he works at the club, a deception that his older brother Rodrick (Devon Bostick) uses to blackmail him and gain access to the establishment.~Perry Seibert
I try very hard to spend time with my daughter who is currently ten years old, and often that is in the form of just being together while watching movies. The Diary of a Wimpy Kid series of movies, and especially this one, is very well done. It's silly and funny but offers some real life lessons. It is a fresh breath of air when compared to so much of the garbage kid shows on cable TV. Unlike so many movies targeted at my daughter's age group, this one is of high quality, including story line, production quality, acting and comedic value. Our whole family couldn't help but laugh out loud together, which in my opinion is a healthy thing for a family to do. Highly recommended movie, and series.
This review is from Diary of a Wimpy Kid: Dog Days [2 Discs] [Blu-ray/DVD] 
I would recommend this to a friend
Rated 4 out of 5 stars
Owned for 1 month when reviewed.
Even though this one is not as good as the first one, it keep my children entertained.
The stories are a great way to capture children's attention, keep them focused, and leave them wanting more. In a digital age where kids prefer playing games on tablets rather than expanding their reading and study skills, this series helps because it will most probably make them want to read the source material that the video is based on. A great investment in their lives, it is!
