The only thing with GSR (while I don't favor that pairing) that bugged me the most was that it caused there to be a lot less Gil/Cath scenes and I really loved their friendship. Though some feel GSR took over the show. With D/L though, the reason it doesn't take over the show is because neither party is one of the main stars. With GSR, Gil was the main character, the leader. With E/C, Calleigh is the leading lady. That may be in part why people are so riled up. Those that feel that GSR took over Vegas may fear that the same will happen with E/C since in both cases one party was one of the leading characters.
