I think "educational" is a bad choice of words.... however, I felt I got my money's worth out of them (and I'd say we own about half of them and Dylan STILL likes to watch a couple of them). But I think they did help maybe expose children to things they wouldn't normally even if it was because of their parents thinking they were getting more than they really were from them.
For example - I knew they weren't going to create my child into a genius... but it allowed him to be exposed to wonderful classical music (granted, I have that on my ipod, so for him, it was a matter of time) and he also knows quite a bit of sign language that he learned from the videos and I used them as a tool to expose to him to other languages (French, Spanish and German) - full knowing he'd never learn them from me - but it's suppose to open a window or something... and he wouldn't have gotten that elsewhere because I can't speak anything but English.
But yeah, "educational" was probably a push. I heard you can only return like 4 though.
