I can't even name 100 pieces of "good" anime and I've seen many over the years.
Most anime is shit. You get maybe 2 quality shows a year and a quality movie every 4 years.
I could name a hundred without too much trouble. Should I? Okay, I will, but don't expect me to put it into any kind of order.

My count might be a little bit off, but that should be about a hundred. Now, not all of them are all time classics, but they're quality shows from a broad range of genres and most are ones that I would watch again.
