    1 2 3 4 5 6 7 8 9 10 6.4/10 X  
Primitive inhabitants of Gamma Trianguli VI worship a God who orders them to kill visitors, from the Enterprise. (50 mins.)
“ This is a classic example of Starfleet beam down procedures, no protection at all, yet they have no idea what's on this planet.

Also, the story itself is contrived horse manure. ” - Paranaut
Star Trek (1966 TV Series)
Episode: The Omega Glory (1968)

Responding to a distress signal, Kirk finds Captain Tracey of the U.S.S. Exeter violating the prime directive and interfering with a war between the Yangs and the Kohms to find the secret of their longevity. (50 mins.)
“ The "Combs" and the "Yangs", really?? Give me a break. The American flag and constitution at the end seal the deal. Bad Episode. ” - Paranaut
Star Trek (1966 TV Series)
Episode: The Mark of Gideon (1969)
    1 2 3 4 5 6 7 8 9 10 6.5/10 X  
Kirk beams down to the planet Gideon and appears to find himself trapped on a deserted Enterprise. Spock on the real Enterprise must use his diplomatic skills to deal with the uncooperative inhabitants of Gideon and find the Captain. (50 mins.)
“ I love that this planet is so over populated that everyone must stand together like sardines, yet they have enough time, resources, and space to build a complete replica of the Enterprise.

Plus in an place like that people would begin to die out anyway. After all, sex would be way out of the question... ” - Paranaut

    1 2 3 4 5 6 7 8 9 10 5.4/10 X  
A group of idealistic hippies, led by an irrational leader, come aboard the U.S.S. Enterprise. (50 mins.)

The "jamming" parts are downright painful. ” - Paranaut
Star Trek: The Next Generation (1987 TV Series)
Episode: Shades of Gray (1989)
    1 2 3 4 5 6 7 8 9 10 3.4/10 X  
Riker returns from an away team mission wounded and infected with microbes from the planet below. He is soon in a coma in sick bay... (44 mins.)
“ Flashback episodes suck anyway, but the main reason I hate this episode is it's just one more example of Starfleet's really stupid non-exsistant safety procedures. Again, they have no idea what's on this planet, yet there they were, no protection what-so-ever, wading through some kind of swamp. Even on Earth this is not advisable, let alone on an unsurvayed alien planet! ” - Paranaut
Star Trek: The Next Generation (1987 TV Series)
Episode: The Outcast (1992)
    1 2 3 4 5 6 7 8 9 10 6.6/10 X  
While aiding an androgynous race who lost a couple of members in an unmapped region of space, Riker falls for one of them, which can lead to trouble if detected, since the alien race does not endorse gender specificity. (44 mins.)
“ The non-gender species themselves make little sense and were written soley to make a point. I can almost buy a species evolving to that point but the fact that they still must, for all practical purposes, have some kind of sexual act in order to reproduce is totally unbelievable. If they were more like the Drak in "Enemy Mine", ok, but that's not the only problem I have here. The fact that they have a problem with these "throw backs" who have gender tendencies is completely unbelievable and exists only so this writer can preach. ” - Paranaut
Star Trek: The Next Generation (1987 TV Series)
Episode: Suspicions (1993)
    1 2 3 4 5 6 7 8 9 10 7.0/10 X  
Dr. Crusher puts her career on the line to prove a scientist's theoretical new shielding technology which may have cost him his life. (44 mins.)
“ This is where the Star Trek writers begin to exist with their heads squarely up their own rectums.
There is no way, 1: the ships doctor would ever organize something like this on her own. 2: they would allow a sentient being to risk himself, not to mention a perfectly good shuttlecraft, on a dangerous scientific experiment that no one believed would work in the first place. 3: the ship's doctor would be the only one investigating a possible murder on board. 4: Dr. Crusher would still have been court martialed. Just because she solved the murder does not mean she didn't put the federation at risk of war with the Ferengi, not to mention disobey a direct order from her commanding officer.
This is Voyager bad. ” - Paranaut
Star Trek: The Next Generation (1987 TV Series)
Episode: Sub Rosa (1994)
    1 2 3 4 5 6 7 8 9 10 5.0/10 X  
Dr. Crusher meets the man in her dead grandmother's life when she tries to put her affairs in order, whom one of the local people warn her to stay away from by not lighting a candle that has been lit for generations. (44 mins.)
“ Another Dr. Crusher lemon. Ghosts now? Really? ” - Paranaut
