All I can remember is this guy and this woman captured by aliens and her arm somehow got detached (I think it was eaten?) And there was a giant white monster alien thing that they where taken to. The humans wore black (armor, I think?) And the planet/moon whatever was red, if I remember anything correctly.
Also, the white thing kinda looked like a big fat spider, and in the end it was captured and studied. I think it was the alien king? It shot webs from its mouth I think...sorry, I was 7, and this was more than half my life ago so sorry if there is any misinformation! Really hoping to find this!
No idea what time it was made, as it was on TV. Maybe 80s, 90s, early 2000s? This was around 2007-2008.
