I recently went to the movie theater to see "Diary of a Wimpy Kid".
I liked the animated bits but I didn't like any of the charecters in that movie...and what makes it so interesting is that's an adaption of a book by the same name.They carried a simple style to the animation but it's satisfying just looking at those bits.The humor is more for kids and it almost felt like something Nickelodeon Movies would make except it's by 20th Century Fox.
I haven't read the book and I really don't want to anyway.
I won't do a comparison to the book and movie but I could obviously tell they changed things but kepted it closer to the book (if that makes sense).
I honestly didn't like the film but only a few bits (live action scenes) I found satisfying.
So overall,decent movie but more a kids movie.
