Pretty good, but not fantastic. Lots of funny bits in every episode however makes it worth watching. Looking forward to a season 2 if they make one. 8/10


Would be much better if Daniel Mays wasn’t casted for the role. Or if they made DI Majors character better. Can’t get past how annoying the chatter is.


The humour kinda reminds me of Angie Tribeca.

About Me

I am Sophie and this is my website.

A little about me 👋 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 (.. binging…) series on my computer on rainy Sundays or any sunny day for that matter 🙈

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 don’t feel like watching it all over again…

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!
