do you know another word for fantastic?
"Before I go, I just want to tell you: you were fantastic. Absolutely fantastic. And do you know what? So was I." So, Doctor. Or Rose, depending on the sentence. Brilliant is good too--one of my favorites.
What? You wanted an actual answer and not just me fangirling over the Ninth Doctor? Fine, if you insist.
Here are a few: selcouth (strange and yet marvelous), mirifical (wondrous and amazing), phantasmagoric (characterized by fantastic imagery), orphic (beyond ordinary understanding), and chimerical (fantastically visionary). Mostly not exact synonyms, but of a similar scope.
If you're looking for something a little simpler, fantastic is a word for which you have a number of good options. Magnificent, splendid, brilliant, glorious, fabulous, wondrous, resplendent... lots!
