These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Anticlimax Boss: The mighty Tobias Bruckner in "Evolution", who could actually be killed from outside his reaction range, resulting in a final boss that consisted of shooting at a stationary man sat on a dinosaur. Heck, if you wanted to be really anti-climatic, just get a tree to fall on Bruckner for a one-hit kill. Yeah, a final boss being killed in one hit.
Averted if you chose to avoid exploiting either the above tricks mentioned, in which case you are going to be in for a hard fight.
Best Boss Ever: Thunder. He's a massive Damage-Sponge Boss that singlehandedly requires the player to conserve ammo for the fusion cannon, but his attacks are tough enough to avoid that he really tests your skills with strafing and dodging. And there's the sheer concept of the fight that makes it cool.
Big Lipped Alligator Moment: The boss in the "Lair of the Blind Ones". Seriously, what the hell was that thing? Adon never mentioned in the briefing, and it's never brought up after the level.
The soundtrack to first game, done entirely on synthesizers manages to stay Uber-Badass and still be classic-video game style at the same time. Thus qualifying it for Crowning music of awesome.
And while everybody and their sixth cousin five times removed seemed to think Turok: Evolution one of the worst peices of crap ever concieved, The Music was absolutely E-P-I-C (especially the Track, Lost Temple).
Listen to Mountain Forest for the Game Boy port of Turok 1. The Game Boy port really combined exploration and 8-bit melody goodness.
The Primagen's elite troopers avert this, they can take a ton of abuse and their machine can cut you down in seconds, unarguably, they're the strongest enemies in the game. Thing is, if not for the fact that by the time you run into them you have an arsenal that can deal with them without much difficulty (tranquilizer dart to stun them allows them to be dealt with easily without a direct fight).
Ensemble Darkhorse: Weapon example, the cerebral bore. While not considered the most useful weapon in the game (while it's One-Hit KO, it only works on living enemies with heads and doesn't affect bosses), that one most players would argue is the shredder, but is arguable the most famous weapon due the sheer gore factor from it drilling into an enemy's head and than exploding.
Even Better Sequel: Seeds of Evil was near-universally rated as being one of these when it first came out. Nowadays there tends to be a 50-50 split as to whether the first or second game is the best.
Goddamn Bats: The designers apparently felt that every cave in the first game needed to have Leapers: Freaked-up demonic monkeys that looked like a deformed kid in somebody's bad acid trip; that did virtually no damage but just kept making this HORRIBLE SCREECH that made everybody who played the game want to lobotomize themselves with a Garden Gnome. Don't believe it could be that bad? Just check out Turok: Dinosaur Hunter LP by Eexecute on Youtube.
I Am Not Shazam: Subverted. With the exception of the original comics and the 2008 reboot, Turok is not the name of the protagonists in the games or the reboot comics, but rather a title that they are referred to. The confusion comes from the fact that in the first two games the characters shout "I....am Turok!" every time they get a extra life. Also, Tal'Set's name isn't mentioned at all in the first game.
Nightmare Fuel: Seeds of Evil and Shadow of Oblivion have their moments.
Specifically, Oblivion's speech when you first enter one of the Fake Portals:
Oblivion: SEE THIS, HUMAN! Powers beyond the comprehension of flesh... have been set in motion. The Primagen must not be stopped. The Totems must fall. The balance must falter. Chaos MUST commence. We are the darkness. We are the unseen. WE ARE OBLIVION! That which has been set in motion... cannot be stopped. Your deeds... Your life... YOUR VERY EXISTANCE... Fall under the great shadow of Oblivion! Your failure is inevitable...
Porting Disaster: Part of why Evolution has such a bad reputation is the awful PlayStation 2 port, which has significantly degraded graphics and framerate issues. The Xbox and GameCube versions have pretty respectable graphics for those systems, but with the PS2 being a far more popular system than those two, that ended up being the version that most people were familiar with.
Rated M for Money: No arguing, this is definitely a series that attracted people with the silly amounts of gore, hell the 2nd game's melee weapons allowed you cut some of the enemies' heads off.
Seinfeld Is Unfunny: The endtrails in "Seeds Of Evil" had an extremely advanced AI for an FPS enemy when the game came out, but stuff like that is fairly common place in most the recent FPS games.
That One Boss: The giant sea-serpent/octopus monster in the 2008 game, with its cheap attacks, rock-throwing abilities and counter-intuitive weaknessnote You lure the monster over an air vent, then hit the vent with a flamethrower to send flames at it. , is loathed by just about everyone who's played the game.
