Well, I guess if you're going to compare it to D&D, you won't enjoy it because they're two completely different games. Sure they're both under the RPG genre, but there are major differences between the two that don't really warrant comparisons. If you already have the mindset that you won't enjoy it because of how much you like D&D, or how different it is, then it isn't worth your time to play it.
However, if you do decide that you want to just give it a try to see how it is, I would suggest looking through some of the other forum threads to see what ways there are to keep it as close to a certain style of playing as possible. I've never played D&D so I'm unfamiliar with how it works, but maybe there are some ways that you can play Skyrim to make it feel a little more like D&D.
Bottom line, if you need such strong persuasion to play it, nobody is going to really be able to make you do that. You just kind of have to make that decision yourself.
