The Romans themselves noted that the games of the arena were often too bloody for foreigners who had not been raised to enjoy such things - and their contemporaries were not exactly 'delicate'. So it's certainly gruesome.

But another matter is that a scene like this, of an unarmed man being torn apart by animals, is more akin to a public execution than the gladiator games - those sentenced to die in this way, noxii, were men convicted of (what the Romans saw as) serious offenses.
