I dont think the standard of reffing is any worse than it ever has been.
I can remember Clive Thomas blowing for full time in a World Cup match in 1978 just as Brazil were putting the ball in the net and not letting the goal stand.
or what about when Schumacher in the german goal tried to kill Patrick Battiston in 1982, resulting in a goal kick.
these two incidents are both over 25 years old and rank alongside anything you see these days (including the goal that never was for Spurs against Utd a couple of years ago).
I think the things that make football less atractive these days are the post prem numpties with little understanding of the game or the culture behind it.
folk who sing "who are ya" or "easy easy" at matches (ashamed to have heard it at Old Trafford recently). jesters hats, face paints and whole stands full of men in their thirties wearing replikits (not just at Newcastle).
