I love this show, I don't care that they say it is just a copy of friends. I didn't like friends, everyone did stupid senseless things. I've watch HIMYM's seasons 4 times and I laugh every time. Those are the Squad Goals.
I loved this show 'cause it's about Green Arrow. I loved the first two seasons, and truth be told I didn't quite like the last one, between the dude that buys the company and felicity adn now everyone knows about Oliver. It's far away from what made Arrow so good. Though I'm not gonna lie, I'll keep on watching it.
Great show, characters and plot. This show has a great story, the way they manage the flashbacks and how you know so little about what is happening makes you crazy, you don't know who is bad or who is good, you suspect everything but what actually happened, although it is quite obvious once you see it.
The perfect thing about this show is its plot twits, almost every episode you end up screaming "Plot twist!!". Great series, just watch it, don't think twice about it.
