Judging from the plot setting of the movie, Alice's ability has not been fully released in the second movie, which can be seen from the two movies Resident Evil 2 and Resident Evil 3. In fact, Alice's ability has not been fully mastered in 3. As for why only Alice died, according to the movie version of the story, Alice didn't die, but Alice helped others escape, but she couldn't save herself because of her incompetence. In the last part of 2, Alice gradually recovers in a container, which feels a bit like an instrument in starship troopers. Gill valentin appeared in the fifth movie. She was controlled by the Red Queen, who was the computer host of No.1 Middle School. Generally speaking, the adaptation of Resident Evil series is a complete failure, which is too far away from the game. It is recommended to see the CG version.
