One: your screen will be filled with beautiful effects and colours. These do nothing for the story, but they will keep your lazy eyes occupied for some 50 minutes. A good example is the eternal use of a computer screen that shows each fingerprint from the database as that print is compared with the one they want to find out about. Yeah, right.
Two: these guys being like real professional Pros, they will engage each other in intriguing Pro talk: "Look, Grissom, these are what we call fingerprints. Everybody has them, and they are different on each person. So, with these fingerprints we can actually find...".
Yup! Exactly like real pros would talk to each other if there wasn't a completely uninformed and stupid audience around.
However, not everything about this show is bad. Some stories work to some degree, and the colours _are_ really beautiful. They use red, blue, green, yellow... all of them colours I've loved since kindergarten.
