I have to admit, that when I watched the first episode of this show, it reminded me so much of The Wonder Years that it was distracting. That being said, after episode 2 and 3, I hardly notice the narration. I think the first episode had a ton more narration because of character introductions and such, but 2 and 3 have gotten progressively funnier, and all of the 80's nostalgia is very endearing to me.
I grew up in the 80's, and this show hit's the nail on the head! The characters are believable and relate-able, the writing is very cohesive and well thought out, and the acting is very convincing and hilarious. I found myself laughing out loud over and over again.
Don't listen to all the haters. Give this show a shot and you won't be disappointed.
