Anything that gets you exercising rather than sitting on your ass is generally good, even road running which can be very bad for a lot of people, I don't mind too much in moderation...however..some of the horrendous form and posture that people display in some of the crossfit I have seen can't be recommended.
Thats without even going into the detail of the sessions themselves that can be at best, non-functional and at worst..the cause of neuromuscular damage.
The modern obsession with training fads is to blame of course.
The proper route to getting fitter for most sports is simply get yourself screened for any anatomical weakness, correct it, get stronger in line with the physiological requirements of your sport (by building pure strength first, i.e: lifting maximal loads, short reps) then for GAA for example, building power by following a general periodised structure of Olympic lifting - Plyometrics/Olympic lifting - Sprint training (linear & lateral..perhaps resisted) along with stuff like box jumps - Speed/agility (or reactive speed), short sharp bursts of speed sessions, stuff like reaction drills.
Could go on and on, but basically think Crossfit can do a lot of people more damage than good.
