Depends on whether Studio Ghibli could be considered anime... In my opinion, it is -- but I guess the first anime series I actually watched would've been Tokyo Mew Mew back when I was real young. (At least, as far as I can remember.)
Well.... perhaps 'section' or 'part' would be more appropriate than 'half'? Not all of the SU fans are bad, but I don't want to try going into semantics on just how much of that particular fandom is cancerous. Trying to dive into the depths in order to estimate the amount is just going to end up...
Legend of the Legendary Heroes is definitely a good, short series to watch if you have the time. And then there's Nichijou if you're looking for extreme humor.
I'm gonna throw the 7th Dragon series out there; even if it's relatively recent... Even if the story is a bit all over the place, it's still an enjoyable experience - at least, it is in my book...
