    "Doctor Who" is a strong first part of the season finale. I did not care for the storyline where Ray was suspected of being an accomplise in the "Angel of Death" murders. It could not have been more obvious that he was innocent. The same could be said for the murder of the reporter. What makes this episode work is the Jekyll & Hyde investigation. That part of the episode is well written and acted. The final scene of this episode does a great job in setting up part two. I can hardly wait. Still the best crime drama. Period.moreless

    In this episode of CSI, the following happens. When a woman named Heidi is found murdered, we learn that Ray knows her. Soon he becomes a suspect in the case, after they find CCTV footage of the two of them together. Although it turns out that Heidi had been following Ray and also has been investigation the Jekyll killer. We learn that the Jekyll killer has been following Ray. As the episode ends, Ray gets a phone call from Nate, infamous "Dick and Jane" killer who says he knows who Dr. Jekyll is. Overall quite an interesting episode. Considering that the next episode is the finale, I just hope that it's better than the one from last season.moreless

    • Title: Doctor Who The title of this episode could be a reference to the popular BBC tv series by the same name. Although it more likely is a play on "Dr. Ray", "Dr. Jeckyll", and the creation of suspense as to who's who, thus giving us "Dr. Who?" If it were an allusion to the original Dr. Who, we'd see "junk" science being proved true to save the day, for example, or other relatively outlandish "science" feats. Those WERE the hallmarks of the original British Dr. Who show, after all.
