You boys are great should also be accepted here. It is a more natural English construction.
It uses a different grammar, though, so I'm sceptical.
"Ti fiúk nagyszerűek vagytok."
Please someone tell me that nagyszerűek breaks down to something other than "big-like" or, as it might be, "bigly"...
I don't know if I can use that word if I think I'm translating Donald Trump every time I do it!
Sorry to disappoint you here. :´)
Nagy - big; szerű - kind of, like. It's a construction a couple of languages use. "Groß-artig" in German, "stor-artat" in Swedish, or the Latin-based "grand-iose".
