The most noticeable improvement when comparing the GTA Trilogy to the original games is how different the environment looks.
Naturally, such a statement differs based on which platform the player is using. The Nintendo Switch is the least impressive out of the current batch when it comes to graphics, so its screenshots don't look impressive. However, a platform like PC can have some stunning visuals.
The environment looks especially good when players compare it to the game's character models. Some characters have had questionable changes done to them, resulting in much online ridicule.
A look at how the remastered GTA Trilogy's environment visuals compare to the character models
The above screenshot shows how much the foliage has improved in the GTA Trilogy, a difference as stark as night and day. The old GTA San Andreas looked flat and lifeless at times, whereas the GTA Trilogy's environment offers a much closer shot at realism.
It's a common sentiment online, as some fans praise the game's environment for looking nice. On the opposite side of the spectrum is the reaction to the character models. Players have been slamming Rockstar online, often showcasing ugly models, texture glitches, or bizarre design changes.
The juxtaposition of the environment and characters is jarring at times. The former is an example of what the GTA Trilogy does right, whereas the latter is what the game does wrong.
It's worth mentioning that not every aspect of the GTA Trilogy's environment is perfect. For example, there are typos in some billboards and signs, such as "AR GUITARS" instead of "AIR GUITARS." That said, it's less of a problem compared to the plastic looks and weird models for the characters.
What the GTA Trilogy's environment does right
The GTA Trilogy's lighting is at its best in several of the game's locations. For example, Ocean Beach looks beautiful with its neon lights at night. The vibrant colors work well here.
One can tell that there are several changes to the overall location between the two decades, but these are mostly positive changes. For example, the foliage and lighting don't look cheap or artificial anymore. Likewise, the smoother textures are advantageous in the current setting.
Why are fans unhappy with the revamped characters?
The previous screenshot and the above Tweet are from the same game. It's an example of how the "smoother look" doesn't work for the characters, making Ken Rosenberg look significantly younger.
That's not even getting to how some animations are buggy and look demonic at times. This problem isn't relevant to the environment, so it simply makes the characters look worse by comparison.
Not to mention, the characters don't look great for a "modern" GTA game, whereas the environment's rework seems more plausible given the current technology.
