I'm sure that it won't take 10 years for fans to warm up to Ray. That would just be people being stubborn. :lol:
It basically just comes down to presentation. I can think of two possible ways the character could have been introduced that would have allowed fans to accept him quicker.
1) Have him appear as a consultant during Grissom's tenure for a longer period of time. Ray was great when he worked as one during "19 Down"/"One To Go". If we had had more of that, we would have seen more of him as an expert in his field and when it came time for him to work for the lab, it would have been more believable for the fans to see him rise up so quickly. As it happened, we got his brief introduction, one ep as a newbie, and then BAM!... Super Langston.
2) More time as newbie. By the end of season 9, Langston had developed all the traits that fans have shown to dislike (i.e. Super Langston). There was a very small time frame where he was allowed to be the newbie. Had the second half of season 9 focused on his trials and tribulations of dealing with the job, instead of already being an expert at a job he's never worked, fans would probably give him kudos for striving to be a level two by the time season 10 came about. What we got instead was some who presented himself as a wunderkind who appears to make the rest of the cast obsolete. Or, you know, Super Langston and his one man show "Mascara" (cue dramatic theme music).
Its all about presentation. I like Ray. I'm sure others do as well. Its just that the character as presented isn't meshing with the environment he's been introduced to. For 8 years previous, we saw a world where hierarchy mattered. Ecklie, Brass, Grissom, Catherine (the people at the top of the hierarchy) all enforced the ranking system. Nick, Warrick, Sara, Greg and others all had to go through the paces. Solo cases, trash runs, lead on case, etc. Each one was given a task based on their experience level. It was what the fans grew to accept and is one of the many aspects of the show that we grew to trust. Now Ray is bypassing that. That is what people are having a hard time accepting - no matter how hard tptb try to make us believe otherwise.
