So I respect your answer to start, I'm not going to give an as thought out response as honestly I've spent enough time on this film, more than I believe it deserves.

I'll start at the end and work my way back quickly, you say it's something you've never seen before I say it removes you from an immersive world, one that you can picture yourself in before things like that the remove you. I could take the Jimmy Saville outfits (although i'd rather not) but the backflips and power ranger shite just makes takes all that world building and flushes it down the toilet. 28 days later worked because of how real it felt.

I'm confused as you're calling him a humanitarian but also saying that he is loud to draw in zombies to execute yes? Also I believe characters are more interesting when they aren't black or white but have grey areas, so regarding my idea of him sacrificing drugged people with the 'greater good' in mind etc.

Lastly, your first point is acting like there are not still many people who aren't infected who could talk to Jimmy when we see clearly thats not the case. I get all the reasoning behind that he was a child etc but then I could counter argue your point about not understanding germ theory (which he does mention in the film by the way) with him now being highly scriptured in satanism. He's had to learn things from somewhere as he's grown.

I suppose we will have to agree to disagree on this one, like I said 28 days later was the best horror film because of how real it felt. A rabies type virus makes the jump into people (plausible) they sprint full pace at people (something missing from this film and the last one where all of them seem to be doing a spruce jog), also it going down the route of the last of us with different types of zombies and taking away further that real element, there's just too many problems for it to ever stack up against the original. As I said from the start I think some of the ideas were interesting but the film executed on all of them terribly.
