Though I know now that Beverly Cleary wrote most of her books from the fifties through seventies, the stories are so timeless because I always pictured them in the present-tense (which was the early- to mid-90s when I was reading them). The characters, the setting, the situations are relative to kids of any decade, which is why I was happy to see Ramona and Beezus (though the appropriate order is still "Beezus and Ramona" in my head) make it to the big screen in, what I found to be, a successful fashion. [Sidenote: I vaguely remember a Ramona TV series from the 80s, and lo and behold, there was one, starring...Sarah Polley, star of Avonlea! Oh the coincidences in this post!]
Anyway, the 2010 Ramona and Beezus has a plethora of well-known actors, all of whom I completely ADORE, and was very enjoyable for this kid at heart. I recommend, for you and your kids!
