The first episode actually seemed very promising and had a great potential. But unfortunately it developed into a series for people who love seeing a lot of laser weapons shooting and spaceships shooting it out.
A series that suffered much by episodes in between that did not pursuit the storyline and seemed not to fit in continuum. Sometimes you wondered why they did not use powerful objects from earlier episodes.
The main characters were:
Captain Dillon Hunt - Name should have been captain Perfect instead. So political correct it makes you want to puke. Strangely enough Mr. perfect have no troubles killing innocent prison guards while he time after time jeopardize the mission and his crew to protect female criminals. Always blaming others for their flaws and never admitting his own even when they nearly get everyone killed. If there is a female in the episode then he is always good for a kiss and more. When he starts kissing with woman number ten you start to see a pattern. It is fine with romance but always and with every woman he meets is plain stupid and annoying. In season 5 he even becomes even more righteous and use every opportunity to tell his crew how bad they handled themselves even if it is his error that put them in that mess. Worst thing is they chose such a bad actor to have the main role. I noticed several times it looked like he smiled when approaching his crew after they just had great personal loses.
Andromeda - The worlds most powerful warship. Still anyone can get unnoticed on board and make every kind of sabotage on the ship. And never does it intercept transmissions from enemies on board to the outside. Sometimes two small space-fighters can nearly destroy Andromeda and other times it can destroy an entire fleet alone. I often wondered how come no one build a more powerful one the 300 years it was gone.
Trance - First 3 seasons she should have been the mystery of the crew. It got fast boring and when you finally get the secret it is really not interesting.
Harper - Character with more potential than always just being the puny scientist. My personal favorite nerd.
Beka - In the last horrible season her role finally flowers and she is permitted to be more than Dillons puppet. She should have been written that way all the time.
Tyr - The only character that developed throughout the series. Unfortunately that was destroyed in the end by incompetent writers.
Nietzscheans - An unbelievable race that never really seems plausible. Unfortunately they have a very big role in the series.
So if you want a series with interesting characters and stories then look for something else. This is very far from good sci-fi. It seemed like the writers ended up not knowing if they were writing a superhero or sci-fi series, and it turned out bad both ways.
All in all I have a hard time understanding why many good sci-fi series die after one season or less and this lasted 5 seasons.
