I actually stumbled upon Person of Interest a couple times, but the first couple episodes were so unlike what I saw I figured it was a different series.
Eventually I realized it was the same show, and was able to watch the first couple seasons with baited breath trying to figure out how it became the show in the episode that I glimpsed before… and if it even was as good as I thought it was years prior.
So maybe watch a random episode in the fourth season of you don’t like season one? XD
edit: it was even better than I remember. It became one of my favorite series, probably the one I still think about the most to this day
