It's been a while since I've seen art for NIMH. Both the movie and novel were big parts of my childhood, and the movie still inspires me to this day. This is a really cute and nice tribute to the series, I'd say.
I'm kind of sad how many people have only seen the movie. If you like the movie, please please please go read the book! It's absolutely fantastic! And a much more compelling story, in my opinion. It doesn't have magic, like the movie does, so Mrs. Frisby is a very ordinary mouse with ordinary mouse abilities, yet still accomplishes great things.
Same! When the magic came into play I was just like ...What????? ...wait a minute. Doesn't this go against half the point of the story? While not really adding anything to it? I really do not understand the decision to add that in.
