So with out a doubt Arcade mode is the most frustrating bit of Tekken Tag Tourney 2 the end boss is garbage and I just find that mode the most frustrating of the lot. I've been still playing it though to unlock ending movies. Then...I had a break through... I totally found out you can unlock ending movies without having to play arcade mode! The "Gold" named ghosts in ghost battles give up a their ending movie if you beat them. Fantastic discovery! Now I never have to play that mode again!
