Yep, that's Leon. Looks like he shaved the stubble he had going for Resident Evil 6. Still has the same hair he had when he was 21. He also seems to be keeping up the tradition of getting a new leather jacket with each appearance.
Rebecca returns for the first time since Resident Evil 0! Or, well, since REmake, chronologically. She looks great. I'm actually surprised it took this long for her to show up again.
Who the... is that... Chris Redfield...?
Looks like all the hard drinking he did in RE6 took its toll. Why can't Capcom decide what they want this guy to look like? Every three or four years he morphs into a completely different person.
I'm convinced that "Chris Redfield" might actually be its own organization of people operating under a single name. Anyway, moving on...
And here we have totally-not-Albert Wesker, who may or may not be involved with creating B.O.W.s of some sort or another.
I have a mixed reception of the CG films. The "feel" of the Resident Evil series works best within the framework of a game, and is given an opportunity to shine through player agency. The earlier titles use a claustrophobic feeling of horror and relative helplessness to sell the atmosphere, whereas the more action oriented titles use a sense of immediate danger and reliance on reflexes to create a similarly thrilling tone.
The CG movies don't have any of this going for them - there are no enemy encounters, puzzles, or even interactive cutscenes to break up the campy horror story that this universe is known to tell. As such, they suffer a bit as a result. A large part of why this is, I think, is that the series is at its best when it tells its story through the files scattered across each game. There are no files in these films - only words and actions. That said, I don't find the movies particularly terrible; they're just not particularly great, either.
It is cool that they are canon to the game's stories, however. Tricell showed up in Degeneration before it showed up in Resident Evil 5, so it's entirely possible that this game may end up linking to the upcoming Resident Evil 7 in some way. We'll see.
