Supernatural is definitely fantasy whereas TWD and Breaking Bad are supposed to be set here and now. Supernatural starts that way but it eventually becomes apparent that Sam and Dean's universe isn't ours. Magic actually works in their world. Prayer is a valid form of communication. Supernatural beings are everywhere. That may make it sound a bit Disneyfied but it is actually pretty dark, full of black humour and, particularly, some heart-tugging relationship drama. You'll either hate it or be sucked right in.
YES. Supernatural is amazing. It's kinda hard for me to compare for you, because I haven't seen TWD and Breaking Bad, but I can assure you anybody will love Supernatural. I think it's indeed pretty similar, only Supernatural characters feel more...fantasy? (well, kinda obvious since it's all paranormal stuff) And the show is funnier, has more gags, jokes etc.
Supernatural is 1000x better than that overrated show that is The Walking Dead.
I didn't like supernatural at all. I found it very juvenile. but I guess its target audience starts with teenagers so that probably explains why I found it too kid friendly. but then, I don't really like the walking dead either.
I love TWD and Breaking Bad. It looks like TWD has some similarities with Supernatural. Would I like Supernatural?
