That was a very sweet flash video. 'Course, the site isn't really geared toward Christian stuff, and power to the site for that, but in all honesty people who are offended by this video can do what other people should do when something offends them and ignore it - there's an entire section dedicated to making religiously offensive material that other people simply have learned to ignore, so it's quite hypocritical to attack a video just because you don't believe it's message.
The animation was alright (anime Jesus? What is this...?), and the voice acting was passable, and the message has been heard before. Nonetheless, it was still very well constructed; the symbolism is really quite effectively placed throughout, and the quoting of a passage about love at the end made it impossible to mistake what you were talking about.
In fact, I will actually agree with some of the more polite atheist messages saying that most people will catch the symbolism perfectly fine without a description (that's what symbolism is for, after all), so you can get the best of both world if you leave a less wordy description of the video (say, for example, this is about Jesus' love... and leave it there).
Otherwise, nice movie - I enjoyed it.
