Yes, Gargoyles was excellent, a rare attempt by Disney to do a serious action-adventure animated series (though that was a reaction to Batman: The Animated Series's success; the earliest plans were for yet another Disney Afternoon comedy). It had a strong writing staff headed by Greg Weisman and Michael Reaves, terrific animation, and a magnificent cast including Keith David, Salli Richardson, Ed Asner, Jonathan Frakes, Marina Sirtis, and many more (including many Star Trek cast members from all four then-extant series). It had rich fantasy world-building steeped in world mythology, and a thousand-year epic backstory woven through British (mostly Scottish) history, including a version of King Macbeth who, despite his involvement with magic and time travel, is considerably more historically accurate than Shakespeare's version. But if you do watch it, skip the final season, The Goliath Chronicles. Aside from its first episode, it was made without Greg Weisman's involvement, and it was dumbed down for Saturday mornings, so Gargoyles fandom considers it non-canonical -- with the canonical version being the comics Weisman did after the series (though those were cancelled after a fairly brief run; they're available as three fairly slim trade paperbacks).
