Combine Ramona & Beezus and Petit Nicolas and you get Diary of Wimpy Kid.
Difference between them, it's that our main character is in the middle school.
What i have to say about the movie? Loved it! It was funny and it's how little kids really think. The actors did an amazing job, kids and adults.
You see how strong a friendship can be no matter the difficulties through time or what a big trouble old brothers can be. How parents can't see what their kids see. There is no something special like it in Ramona & Beezus where Ramona was trying to save her family, but it's still so good. I'm totally sure you will enjoy it!
(<--------that's here in Kick Ass)And bigger surprise for me was Chloe Moretz (also know as the killer Hit Girl at Kick Ass or the vampire girl at Let Me In). She was so small and different in Kick Ass and here was wow! She showed to the world what a great actress is and how many different roles can play. All the time i was looking at her and i was "no way is Hit Girl!". I'm kinda dissapointed she is not in the next Wimpy Kid movie. (that's here in Wimpy Kid----------->)
(and that's her in Let Me In vvv)
Oh, didn't i tell you? There is a Wimpy Kid 2! And it would be so much more fun! Parents leave and the big bro is responsible? Awesome!
