the 4th season of the OC was good IMO as was first. I lost interesting in S2 of the OC and especially during S3.. It was refreshing in S4 IMO..
OTH was good in S1 yes
S2 was pretty good too, S3 was too many twists and drama and same goes for S4. I wonder how this ´into the future´ thing will work out for the show.
