I've enjoyed reading everyone's comments, thoughts, theories and general opinions. I had not noticed any recent comments on the relationship between Caleb and Hannah. It seems as though all the guys and girls became more like best friends than boy and girl friends. They used to be so physical and loving and caring about each other. Now the caring is still there but it's more like a close friendship than a love relationship. For example, when Caleb came to Hannah's house to tell her that the police were on their way to arrest her, there was no loving hug and kiss as he came in the door to give her major bad news, and there were no reassuring hugs after he had told her the bad news. What the heck?! Hugs should have been absolutes with that! We've seen them together a lot over the last season, but where's the fun and teasing and hugs and kisses and all that we had in Season 1? I loved the old twinkle eyed Caleb who was so delighted with Hannah. I know he had to have been changed by his experiences at Ravenswood, but even when he first came back and was so badly traumatized, he held Hannah and kissed her. I recognize that PLL has gotten seriously dark and that that atmosphere might influence the relationships to some extent, but I would hate to see them ending up really close friends, and with Caleb just being the big brother the rest of the Liars never had. Oh, and for Pete's sake, let's not have a Caleb/Spencer romantic relationship just to confuse things (even more) and add filler material.
I haven't seen "The Melody Lingers On" yet so I don't have anything to say about it but I was very interested in what everyone said in comments about other episodes with all the ridiculous research mistakes the writers had made in the science, law, timing and so on. It gets really frustrating. The lawsuits in Rosewood that would have come from all the dumb things that happened on that show would need a whole separate season to cover!
