My bigger concern would be how he treats you when it's something YOU like as opposed to something HE likes.
My husband and I have a lot in common, however, we have a lot that we both like that the other doesn't. I respect the fact that he has other interest that I don't share and he respects the fact that I have other interests that he doesn't share. I don't mock him and he doesn't mock me about those interests, we pursue them and enjoy them and respect each other's opinions about them.
And the 2 tv thing doesn't hurt either.
