While good points, I have to disagree. I find the original better due to how it tells its story more in depth, while GoO kind of just goes through the general highlights of the game. I think I prefer her mourning over Alfred, given that he has always been her loyal drone, and the loss of him, while not setting her back, does affect her enough to the point where she wants to know who did it so she can use them for her twisted experiments. I agree more regarding the voice acting, especially so I dont have to listen to Steve's Canadian "sorry." The Wesker portion I think is somewhat important considering the next point he physically appears in is Lost in Nightmares (timeline wise, other than that its Umbrella Chronicles, which explains why he has powers. Not counting 4 because he only sits in a chair.) In this game it reveals he has a become a bioweapon himself, but he is only wielded by both his own and Spencer's ambitions. If he wasn't shown outside of a few scenes where he either laughs or stares at Chris, it comes out of nowhere and feels lame, not to mention that Umbrella Chronicles would probably not have followed his story the way it does because it wouldn't need to explain how he came back, nor how he got his powers, as they wouldnt be known to the player. While the albinoid is an interesting concept, they shouldn't have made it so hard to fight. I get you can just grab it and go, but that just drains healing items and is annoying in general. Maybe make it a puzzle like the Plant 42 boss fight for Jill. The backtracking is not an issue for Darkside because its a rail shooter, and any backtracking done always has new content. Its not even really backtracking because you cant move the characters to the locations. And the Rockfort Island Chris section just being gone kind of removes the impact gained from following Chris as he hunts for his sister in hostile locations, showing his love for his sister. In GoO, he just shows up after being contacted, somewhat lessening the contrast of the sibling relationships of both them and the Ashfords.
In my opinion, while the og game is a much more rich experience, the retelling is a great way of experiencing the story without the story empty sections of gameplay caused by exploring rooms and trying to solve puzzles. However, if you want to have a good understanding of the game and its themes, I would point you to the original every time, or at least a cutscene movie on youtube.
