This is pretty bad. More than anything, I just found the plot boring. I didn't care about any of the characters, and it felt like the production made minimal effort to correct that until the final 10 minutes. There was some extremely clunky acting (possibly down to the direction as, at other times, I thought the same actors were alright), as well as some odd dialogue. The stupid Sontaran was fun. Characters explaining to a Sontaran what a "female" is, and introducing the term "sexually pair bonded", not so much. Apparently this was an extremely rushed production. It shows.

On the positive side, I thought that the sets, costumes and effects looked pretty good. I quite liked the Sontaran design! However, these small positives were not enough to redeem this for me.
