This.
I like short joke-comics, I like funny GIFs and Vines and so on as much as the next person - but I also get deeply and emotionally involved in longer stories.
They're different kinds of enjoyment. The shorter bursts are like eating candy - while longer stories are like eating proper meals. I love candy, it makes me happy, I'm gonna keep eating it - but I'm always gonna want to eat proper meals, too.
I read a bunch of gag-strip comics regularly - but I also watch One Piece, an anime that has 700+ episodes. I've been watching it for 12 years. I read Moby Dick for fun. I am a huge fan of Friends at the Table, a podcast in which a bunch of friends play tabletop rpgs together - and their two seasons so far add up to 100+ hours straight of listening. And when I say I'm a huge fan, I mean I sometimes have to pause the episodes because I'm crying too hard about the fate of minor characters.
There is a special kind of joy in getting to immerse yourself in a larger fictional world, for many reasons. There's more space in them to explore different aspects of the characters and the story, there's more space for speculation, there's more space for ideas, etc. etc.
That's not to say that longer stories are inherently better than shorter ones - they're just different, and I like both kinds.
