Same thing happened to me. I didn't think much of it when I first saw it but it was obvious since when it was on the TV I was like 10 or something so yeah... But I started watching it again 1-2 years ago and I absolutely loved it and felt such a strong connection with the main characters. Definitely targeted to those who are about or just finished highschool otherwise it doesn't have the same punch to it since most of the time while I was watching the episodes I went all "OMG YES! THIS HAPPENS! YEAAAAAH". Hopefully you'll enjoy the fifth season and the final movie. Brilliant shizzle.
