First rule of thumb about these boards:
no matter what the topic, you will find completely divergent opinions! there is no one restaurant, resort, etc. that is completely 100% loved.
That said:
We gave Tony's another try in August, after having taken a couple of years off from it. We were delighted with our lunch -- everything was very fresh, CM was great, etc. We will eat there again!
Please realize that ALL WDW restaurants are trying to please the middle of the road crowd. No ultra authentic cuisine of ANY kind is available; even at Epcot you are getting Americanized, homogenized versions of a country's cuisine.
If you judge Tony's against the most fabulous Italian place you've ever been to, you will be disappointed. If you judge it based on being theme park food, you'll probably be pleasantly surprised.
