How much is normal for a groom to be involved in?

I'm a groom and I'm getting married in a couple of weeks. My fiancee has picked most of the stuff but I played a very active role in deciding the venue and the menu. I don't care about her dress, the bridesmaids dresses, flowers, centerpieces etc. I do care about my friends having a good time and having good food. We have a high end wedding planner so he really just gives her the options and she picks something and then tells me about it. If I don't agree, she picks something else. And so on. Nothing "groom zilla" about it.
