I watched it. I liked it, but didn't quite love it. Some random thoughts and asides in no particular order:
1. I think they rushed it a little too much. They could have spent a little more time playing out the drama, political and emotional, of an alien visit. Having most of the main characters figure out this is a sinister alien invasion and discovering the secret identities of the visitors-in-our-midst in the first episode was a really profligate waste of dramatic material.
2. I really hope they don't lose the scientists-as-Jews plotline from the original series. I thought that was a great part of the original miniseries.
3. If I were 17 and the super-hot alien blond wanted me to put on a German gay disco doorman's jacket, I would have done so.
4. Scott Wolf is just hard to take seriously when he's not crying over Jennifer Love Hewitt in Party of Five. Maybe he'll improve, but I fear he may have a Mickey Rooney problem in that he won't be able to play a non-teenager until he's 60.
5. Alan Tudyk is awesome because he's awesome. But he'll be under-used and killed
