My son recently turned one so we started putting it on in the background. We ended up paying more attention to the episode than to what we are trying to do with the young lad!
Edit: if you haven't listened to the extended intro, you need to do yourself a favor and check it out.
Nice, a bit young to start watching Breaking Bad, but I watched it when I was 14 and I turned out fine so doesn't seem like that much of an issue, also I agree, the extended intro song is awesome.
I have fond memories of cartoon intros and like listening to my favorites sometimes. I can always appreciate a banger of an intro, even on something new.
