What I liked most about the show were Horatio´s facial expressions in the first 2 or 3 seasons. Caruso is an amazing actor, I love his acting, how he can express his feelings by coughing, avoiding eye contact, swallowing, moving his lips, eyebrows, etc., we can feel when he is embarassed, when he cares, when he is sad. I know that people usually comment on his sunglasses how he keeps putting them on and off, but when you watch his face while he talks to someone he cares about, he is a much better actor than anyone from the current cast. Calleigh sounds absolutely artificial all the time, Eric shows no facial expressions at all, his face is always the same and I really dont like Adam Rodriguez´s acting. I am not going to comment on the others. I just wanted to say that what kept me watching the show was the unspoken relationship between Horatio and Yelina. Something was going on between them. Everytime they looked at each other it was more than just a look. They should bring her back on the show.
When Horatio´s relatives were on the show, it was great, I loved it. Now, with them all gone, it is boring. They are just catching the bad guys but we do not learn anything about their private lives. All the family members of all the CSIs are gone. The only reason why I still watch the show is that I am hoping to see more episodes with H and Kyle, H and Yelina, H and Ray Jr., maybe also H and Suzie or Madison, Ryan´s relatives, etc.
