One thing in Spartacus's favor is that he didn't rise from the dead, he didn't even walk on water, turn water into wine, heal the blind, cure the sick or perform any other great violation of the laws of nature.

Having a history of naturalism tends to augur more for his historicity, IMHO

The Plutarch link above does say:

"When he first came to be sold at Rome, they say a snake coiled itself upon his face as he lay asleep, and his wife, who at this latter time also accompanied him in his flight, his countrywoman, a kind of prophetess, and one of those possessed with the bacchanal frenzy, declared that it was a sign portending great and formidable power to him with no happy event."

Not quite as grandiose as returning from the dead or murdering fig trees using only the power of his mind, but still a bit mystical sounding. Mind you, I know about as much about Roman history as the average American college graduate or in other words next to nothing.
