Agreed; a note-perfect homage by people who loved what they were parodying, same as the Weird Al thing I mentioned in "UHF". I also really liked what Tony Shaloub did in that movie; we had a chief engineer with the same deadpan laconic delivery about dire things:
"Captain, my guys down here say the hyperdrive is about to blow up or something, so..... you know, FYI.... might want to, you know, slow down..."
My wife also really loved the makeup and effects work for Saris the bad guy. I appreciated that some guy went to the trouble of making up an SAP audio channel on the DVD that was all in Thermian for the whole movie.
If you look closely, a young Rainn Wilson from before becoming Dwight on "The Office" in in there, and has like one line, as one of the Thermians.
