Giving the show 4 stars was a bit kind, but it is more enjoyable to watch than the first season. There is very little continuity and all connections to the 1953 movie and the aliens from Mars are completely erased, that is except for one episode that takes us back in time, and that doesn't make sense, but then this show didn't make sense. It came at a time when TV company's patronised sci-fi fans and thought we were all stupid and would take anything thrown at us.
The Martians, the Morthren, the Mortex, who could make sense of it, did the aliens themselves know who they were or where they came from. But at least they acted like 'evil bad guys' so our heroes were obvious to us.
Gone were 2 characters from the first season and a hunkier Adrian Paul was brought in to take the central role. At least his acting wasn't quite so wooden! Like I said before, not as bad as the first season, but then the first season was so dreadful at times it was 'laugh-out-loud' funny. This season is more watchable, a trip down memory lane to the way TV was in the 1980's, but don't expect anything logical.
