It's arguable. The ludicrous design and power differential of the Narada are the strongest pointers since it's entirely possible that a side effect of working on the mining ship is hair/ridge loss.
I think they could probably have made the Narada a more credible threat if Nero had been portrayed as intelligent rather than just awesomely powerful. As a renegade with future knowledge he could have gathered some interesting forces to his banner in the 25 years he has to hang around. I realise that they didn't have a whole lot of time to spend on him because they had to introduce a lot of characters but it was a bit of a waste.
