Thomas and Friends

Whenever I see "Thomas and Friends", I honestly do not see why kids love this show. I bet they have different perspective than adults. But I don't think I would've liked it if I were a kid. All kinds of questions arise in my mind...

What aspect of this show attracts kids so much?
Do kids love more realistic creatures(3D) than just flat cartoon animation characters(2D)?
What color does kids like?
What themes or stories kids like?
What's so entertaining about this?
