^I don't think being critical impairs my ability to enjoy the show at all. I will shower with praise when it's good and I will criticise when it's bad.
I was very glad that they didn't make a total villain out of him in order to get rid of him again. I was really worried that they would make him Mrs. Bates' killer.
I'm not sure I agree actually because I feel like Mary is rather sensible/pragmatic in nature. So even though she's accustomed to certain things, she could adjust - if they made sense. But Carlisle complaining about the servants was actually not a modern concept, but rather belonging to the "old money" system. In fact, I feel that the biggest obstacle - aside from Matthew - is the difference in personalities. Mary appears aloof and slightly haughty but in reality she has a big heart. Carlisle appears ruthless - and he IS pretty ruthless. Because that's how he has amassed his fortune and runs his business.
I do feel that he wasn't treated fairly -- but on the other hand, he did blackmail Mary so there's a limitation to my sympathies. I did however, get the feeling that he might not expose Mary after all. Either that, or he will and it will be something for Matthew and Mary to overcome in S3.
I did find it interesting that he said he loved Mary. Because I didn't think so and I never saw the basis for it since they crashed so much in personalities. (And not in the playful way that M/M did in the beginning.) I think he thought himself in love so in a sense, I suppose there is truth to his statement about him loving Mary a lot more than she loved him. Because she didn't at all, nor did she delude herself into thinking she did.
