So this wasn't the best sci-fi series ever to come on television but for some reason I began to like it more and more as the series progressed. And yes it is cheesy, but so what, just don't take it too seriously and I'm sure you'll like it. It was never intended to be up there with the likes of Battlestar or Farscape but it's still a good series with some fun characters.
When it first started off I wasn't to keen on the concept of a wormhole from Earth to Mongo but it worked out quite well in the end, even if it was kind of a rip off of the Sliders idea. Also, some people complained that the stories were always on Earth instead of Mongo, but as it went along, the storyline shifted more to Mongo and the story revolving around Ming and his daughter Aura (who is hot by the way). There was also a lot of great action too and gunfights. One of the best performing character's would probably have to be the Ming, the benevolent father (played by John Ralston). He made his character seperate to the other Ming I remembered and I appreciated that. The other actors did a good job but nothing too special.
Anyway I overall recommend this series but don't put it down until you've stayed until midway because it does improve.
