Spongebob without a doubt. It's been able to immerse itself into multiple generations and pop culture for almost 20 years, and I don't see it ending anytime soon
Unfortunately Spongebob... You can't really compare a tv show that's been going for 20 years to a movie series with only two films. I hate the Spongebob series and love both Finding Nemo and Finding Dory, but this question is just silly.
