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.
Anti-Climax Boss: In the PC version, the final opponent is Doyle, a weak scientist armed with a P90 and hiding in a control room. He goes down in one shot. Then again, at the beginning of the final level, you fight Big BadClimax Boss Mutated Krieger, who puts up a much bigger fight.
...And he's not much of a threat either, if you fight him by getting in close like you fought all the other giant trigens.
Alternatively, you can just shoot him in the crotch, as he takes massive damage if hit there (who doesn't?) and goes down after only a handful of bullets.
The monkey Trigens. Since the shotgun has little to no stopping power against them, if they start their leaping attack and aren't dead by the time they reach you, you can wave goodbye to half your health.
In Instincts, there are Kamikaze Trigens, who run at you screaming at the top of their lungs and blow up in your face, killing you.
Plot Tumor: The Detective Cordonís investigation of Heatherís death. Itís not badly written per se, but it goes on for too long, with little progress or significant character development. The eventual revelation that Lee was partly complicit in her death and was responsible for covering it up just doesnít elicit much emotion.
Unintentionally Unsympathetic: Will Grayson. His superior makes a very good point that his obsession with Mitchell Roberts is destructive and the methods he used to gather evidence were deeply unethical. Sadly, once Roberts escapes, he is treated as being right all along in his methods and he never gets confronted by either Christine Fell or someone else.
