This is quite a difficult title to review. It sucked me in and pulled me along through it's twists and turns but I skipped a fair bit. So what did I like?

This isn't a typical Drama relying on the usual cliches, though of course it has familiar elements. Cinderella story? Heart warming family drama? Revenge story? Romance? Corruption? Seperation?
This ride takes you through many places and the fact you are never quite sure where it'll take you next is part of it's charm.

The humour is surprisingly good, I laughed out loud regularly and chortled more often. As others have said the humour can be a little dark and twisted at times leading you to curse and laugh at the same time in places.

The acting was exceptional all the characters coming to life with seemingly little effort. There are many faces you will recognise in this ensemble cast and a lot of talent on show. Yoo Joon Sang and Choi Yeon Hee were excellent, portraying the terrible In Laws that you should love to hate with enough humanity to make you never lose sight of them as people. They are the focus of the show and they carry it well.
Go Ah Sung was amazing as Seo Bom, following her journey and character growth was a joy.
There has to be a special mention for the baby as well, watching his interactions with the cast kept bringing a smile to my face, they obviously spent a fair bit of time together.
Only Lee Joon really disappointed just feeling substandard in comparison to everyone else.

This program also contains one of the best birth scenes I've watched, it got the point across without seeming too forced and unreal and I actually watched it all the way through, the humour helped.

The Music I really enjoyed, it had me bopping in my seat on a number of occasions I even liked the opening number enough to look it up. The spooky discordant music was a little overused but at least there weren't any dreadful ballads thrown in. Poongmoon Gypsy made me jig everytime it came on.

What I wasn't so keen on was the corruption and political stuff I skipped through plenty of that, occasionally missing plot points entirely - what happened to her leg? There were also a few episodes which seemed like filler with nothing much happening and not enough humour to pull you through.

As has been noted by others the ending is rushed with too many elements being resolved too quickly, apparently due to two episodes being knocked off the run at a late time. Which makes me regret the filler episodes even more.

I would watch various bits of this again, The headbutt! so unexpected but perfect, the duck and run, Hyun Soo telling it like it is and so on . Maybe in a year or two I'll settle down and watch it again.

TLDR: Worth a go if you fancy something different with laugh out loud moments but no need to force yourself to watch every second.
