About Me

I am Sophie and this is my website.

A little about me ๐Ÿ‘‹ I am a marketing student in Paris. I love spending afternoons with friends in a cafe or a park.

But more than anything else, I love watching (.. bingingโ€ฆ) series on my computer on rainy Sundays or any sunny day for that matter ๐Ÿ™ˆ

I must have watched hundreds of shows by now, from romance to science-fiction series. Often I like to go back to a show I enjoyed. But I donโ€™t feel like watching it all over againโ€ฆ

I created this website so myself and others could find the best episodes of our favourite shows. As of today, I have about 1,000 shows on the website with votes and rating coming from fans.

Hopefully, you can join me from your sofa and enjoy some nice TV!
