I really liked SEED Destiny!
First I saw Gundam Wing when it first came out on Cartoon Network probably over 10 years ago now, then later saw Gundam SEED and G-Gundam few years later, followed by earlier this year I saw Gundam 00 and Gundam Seed Destiny.
Personally I loved them all. Other than that I could count the Anime I've seen on one hand.
Dragonball / DBZ - Loved this, saw DBZ in my early teens and was obsessed with it. Later saw the original Dragonball and loved that too (if not more), then I saw DBGT and really didn't like it at all, meh.
Ninja Scroll - Some movie I saw when I was a kid, thought it was awesome as ****, it was the first anime I'd ever seen.
Naruto - I started watching this this year, loved it initially but the ridiculous ammount of filler that comes in and continues right up until the end of the series really pissed me off. I've heard about filler in anime a lot and that was usually what made me put off watching it. That said I pushed through to the Shippeden and it picked up on the storyline again, only watched a couple of episodes so far. When you aren't being bombarded with filler this is really great.
Not really sure what else I would like, the filler really pisses me off. Gundam didn't really have a lot of filler, maybe 1 episode out of the whole 50 in a series. Would love to see more of it but I don't think there are english dubs of the other stuff.
