Do you like filling out forms built with Typeform?

I recently noticed Typeform (https://www.typeform.com) blowing up. I have personally come across many companies using them for surveys and applications. What is your opinion of forms built using the service? I only ask because I find them unnecessarily long and drawn out, and a chore to fill out compared to just simple web forms.

However, the popularity makes me think that I am in the minority, so I would like to hear your thoughts. If you really like Typeform, I would love to hear exactly why because I just don't get it myself.
