The battle at the end was pretty cool, though it irked me a little to see Tiberius fighting and killing the hardened badass pirates and Spartacus' guys. His ass was immediately whupped by Crassus' sword instructor, yet I'm supposed to believe that he could hold his own against pirates and former gladiators? wut
;__; what
Crassus' instructor was a champion of the arena that was purchased at great cost.
The guys Tiberius killed were probably not even gladiators. A lot of the slaves they've recruited and trained for their army used to be miners or do other manual labor.
