I'm glad it's not just me. I was afraid I might be harboring some deep-seated puppy-kicking tendencies. I thought Peter was bland. He could've been replaced by a hatstand in several scenes and I wouldn't have noticed.
As you get to know them better I think you will develop a burning desire to inflict a painful death on Peter and a swift kick in the butt and a wallop upside the head to Clara while saying, "Wake up you limp, wet doormat."
:O)
