Over the years there have been a number of good scifi shows cancelled and in interviews after the show the same reason is regularly cited for cancellation, that is, the special effects and constant new set changes are just too costly per episode.
I wouldnt be surprised in the least if this is the thought process behind the change because how much can it cost to rearrange a bedroom once in a while? The same ship hallway that the sponge head alien was killed in in a hate crime this week is perfectly suitable for the next weeks episode where the captain rapes the green alien girl.
In other words, someone has decided to kill the franchise to try and get rich quick and weapon will be poorly casted and written sex and murder between the crew.
This describes what I've been complaining about for all new TV shows. They start out with adventure and the lead star is male; but, by the end of the 1st season, a female becomes the boss and all they do is talk, talk, talk.
I just want to watch an action male go on an adventure to do some good. Please! (And, I don't want to watch sex with kids and friends in the room.)
