When i first watch the anime, i couldn't stand the lewdness and stupidness. But as the story progress, i grew to love the characters and become quite interested in the story. In the end, i am sad to see VDM ended. But at east they left it open ended. Happy, but several thing seems like not yet resolved.
In a way, VDM reminded me to Cross Ange. Both of them are a wild ride, but if you stick to the end it's somewhat satisfying and fun.
