Shows with GREAT ideas, but bad execution

I know that this is based off the American movie, but as a remake I think it would've been amazing to see more school with the kids scenes. Because imagine how funny that would be,  a mentally 40 year old guy failing high school and even better if he had gotten caught up in random situations that made him question his mental age. 

this would've been so good without all the unnecessary extra characters or backstory,  similarly to angels last mission these type of shows just add too much dramas in my opinion. Having a light hearted romance of a man cupid just falling in love with someone with no dark backstory or neither of the characters having unnecessary fights would be so comfort drama worthy.

I actually really like this, because there aren't many dramas focusing on how widows were treated in the past and this is new!

I loved this at first because everything was so unexpected , but after episode 2 everything gets boring. The whole concept of someone turning into a serial killer by accident  is actually quite new in Korean dramas, and it would've been better if they were younger in age and also cleaned up the mess they made. (Just imagine how many edits tik tok would make of them) 

So many people were hooked! But after ep 10, things started to just get boring, either the new villain and everything. This drama could've easily finished at 12 episodes while the whole Fandom was freaking out about it. 

If she didn't have a crush on him when HE WAS A KID, this show would've been rly good. A trope of finding your loved one after your past life self died sounds so interesting
