What should I do? (7)

So, I've been generally interested In Gravity Falls for a while. I watched the whole series and its really great and a really awesome series. The only problem is if I join the fandom, I don't want to be the person that leads other people in and completely ruins it for others that liked it in the first place. I dont want to ruin anything for anyone whatsoever, but I really like this show. Should I join it or not? I really dont want to ruin it like I've said alot now.
