That opening was intense and I had the feeling, inspired by Jurassic Park. It certainly reminded me of it. In a good way. Vicious but intelligent creatures chasing down a doomed man in the dark, making him believe for just a moment that he is safe until they strike.
And while I may not be in the camp of people with any serious reservation on Enterprise, I like your interpretation of it so far. Specifically the way the technology is shown to be much more primitive here which makes the eventual progression to the TOS era more logical.
