I understand what you mean also. Summer Strike was ruined with the murder plot. I don't like CCR that much, so…
Oh, Summer Strike :( It could also do without a stupid murder plot. It is a really disappointing thing they keep doing in kdramas. It's as if they don't think the main story and relationships and character development can stand on their own and be interesting to watch, so they dump all this outlandish murder mystery plotlines to keep things "exciting". I hate that so much.
Absolutely disappointing, to be honest. I am really surprised this drama has such positive reviews. My main issue with it: this is yet another drama which is ruined by a nonsensical murder mystery plot which is not needed and does not bring anything to the story. Cut it out of the drama and it won't lose anything at all.
