I thought Beltran was good much of the time, and he really sprang to life in the tense action sequences, even if there wasn't a lot of physical activity going on. You can hear it just in his vocal delivery in some scenes. But if he was stuck as the reacting character in dialogue scenes, he sometimes dropped into a monotone when all he had to do was say lines like "Aye, Captain", "What do you mean?", or "Of course." But he hated "Shattered", where he was the primary character.
