He got everything..
Mic Skills, In-Ring skills, Fitness.. He is still Young.. Already had great feuds with most Top Wrestlers..
He will be in WWE for a decade from now, atleast..
Simply put, so many people like Randy Orton because he is that damn good!
I like Orton because I think he's talent and despite all the hype he's getting, he's still underrated in the sence that he's actually a better wrestler and performer than he's allowed to be in the WWE. The storylines he's in or ppl he's fighting recently are always with ppl who cannot wrestle like Batista or people who are non-wrestlers like Vince and Shane or ppl who are retired like Ric but Orton of course have to sell for or the king of burying talent HHH; therefore it's hard to put on a good wrestling match if his opponent can't fight or if his opponent is set out to bury him.
Orton can have good matches if he's booked in matches or storylines with others that can fight like with Edge back where RatedRKO broke up or even further back when they were fighting for the IC Championship, or his feud with the Undertaker, or mini feuds with Shawn Michaels, Jericho and RVD, also when he first won the World Heavyweight Championship from Benoit by himself in 2004.
