That looks like fun, let me list something too.
If you happen to think the violence and nudity was used in good taste in this anime, there can only be one reason:
1. You have no taste
I guess you need to be more creative then, if you can only think of those 3 reasons. I know way too many people who didn't like Elfen Lied for numerous reasons other than the three listed above.
This is just one example, which I agree almost word by word. (apologies to the reviewer for linking it without permission).
