DRS (Hawk-eye + Ultraedge) has transformed cricket in my opinion. Where before, one erring umpire can change the course of a game, now there is the option to challenge calls. And guess what, if you land up in that 50-50 umpire's call territory, you don't lose the challenge, which is fair. Compare this to the officiating in a modern NBA game and it is night and day. Refs have made NBA games almost unwatchable IMHO. Even if you win a coach's challenge, you don't get to retain it, forcing the coach to keep the challenge for crunch time even if a foul-call is egregious.
