The story and its themes are inspired by Homer's The Odyssey and Virgil's The Aeneid. In other words, for an animated flick about bunnies, this film is dark, depressing, violent, and totally screwed up. Despite my love of the old Greek and Roman tales, I had a few difficulties getting into the story. I couldn't tell you why, but it was just something about it that didn't click with me.
It might have been the characters, as I had a difficult time for a while telling them apart. They did have their own characteristics, but there were still plenty of times it was difficult remembering which rabbit was who and what their personality was (if they had one) and what their role is in the story. Couple that with trying to mentally compare it to its inspiration, and I found myself lost for a good chunk of the movie. Even after I figured them out, I still couldn't much get into them. Perhaps it was the lack of differentiation or emotion in their voices (partly, anyway).
But I think it's the animation that needs to be discussed here. I've never really seen anything like it in a movie before. It's quite unique (Side note: how do you catch a unique rabbit? Unique up on it!). It almost looks like a painting that's turned into animation. But a really trippy painting that starts wigging out on you after you take some hallucinogens. Because this movie ends up in some very bizarre places visually. It sometimes drifts smoothly into almost a dream-like or nightmarish state where everything is off-the-walls, weird, or terrifying. It's also one of the most violent animated bunny movies I've ever seen, and the animation of violence and blood is both unsuspecting and quite well done. Apparently people still complain about the film's PG rating, and it remains today to be the most violent PG animated film ever made.
On the whole, though, I didn't really dislike it. In fact, once I got into it, I did enjoy it--even if it got really crazy at times. I particularly liked the character of Bigwig, as he was a pretty badass bunny. The animation was good and really interesting, which allows it to flow in and out of those strange sequences without seeming out of place. I doubt I'll watch it again, as I wasn't really in love with it, though I can see why somebody would be. It just wasn't all for me.
