This show is alright I used to watch it in High School and decided to re-watched it again as an adult, There's something off about it, I'm not sure its kind of like they mixed together tropes they think teens like and created a T.V series the show seems a bit arrogant to me, you could tell they thought they were going to go on longer than they did and I'm surprise it didn't. They had everything a teen would enjoy drama, love, etc.
Sometimes the acting seemed off, Charlie feels like a Disney actor, and here come spoilers you've been warned, The way they had him go into the coma was pretty lame even when I was 16 and found out how he went into a coma I was disappointed. it was so forced not touching at all. The woman who plays Charlie's mother is a terrible actress, so is the husband. The worse episode would be the one with Bella Throne whenever Bella Throne shows up it usually goes down hill.
Anyway the show was alright not the best, maybe if they weren't so arrogant with the show it would've lasted longer. Maybe if they didn't use so may cliche it would've done better.
I just can't exactly put my finger on it but its off just like that Netflix show "Everything Sucks"
