Did You Know?


The thymus is a type of lymph node located in the sternum just above and behind the heart. It is primarily only active during adolescence and begins to atrophy during puberty. Its function is to produce T-cells which are a type of white blood cell that acts as part of the adaptive immune system, which means it is one of the cells that targets and destroys viral and bacterial organisms marked by antibodies.

When entering the holodeck to look for Geordi they had to spread around to find him. It would have been much simpler to simply end the holoprogram. See more »

Horrible writing, what was the director thinking?
22 January 2021 | by javiergarconSee all my reviews

Executive Producer Rick Berman did his job, but the director, Winrich Kolbe, is to blame for my frustrations. In reality, the writers added to this frustration, and you will recognize their crap work on other television series Brannon Braga and Tim de Haas omg. Are they the worst writers? I hope they have gotten better writing or have found a better passion because obviously, this wasn't it. Where to start? Jordy LaForge always acts like a weirdo pervert like Bill Cosby! Why? What is going on with this character? He is acting like a close friend, but then you get this dark feeling it's sexual. But let's move on because I love Jordy La forge character, and I love the actor that portrays him because he is a great actor that was given horrible lines and horrible directing. So why the bad review? There were apparent moments like the shuttlecraft blowing heading towards the planet... Making up excuses, we are too far for a lock on or can't do anything. Omg, you have a starship faster than a shuttle that can warp next to the shuttle, and you can't be next to it? They are not even traveling there. They are already in orbit in the system, and the storyteller failed. Then there is Jordy Laforge's DNA being rewritten, and he didn't need his visor anymore! Wow, and then when The Doctor heals him, he becomes disabled again? Horrible writing! This should have been that epic moment that he would have regained his eyesight 100%/if, not more. The horrible Directing of these scenes that are chopped up and end up all over the place should have been a two-day episode. Shocking? I love all the other episodes, but this one failed to captivate my feelings because they think I am an idiot and did not graduate from science.
