I don't mind a remake

But now when we have seen this movie, and at least one similar one, we all know how a human look inside. So why not explore a different organism the next time, liek a plant, for instance a sequoia, a cactus or a water lily? That would be amazing. The only problem is; why should someone send someone in there in a submarine?
Or if someone could come up with an excuse, what about travelling through fungal hyphae under the forest floor, lie some kind of natural subway. And then, travel through the water film that is present in most soil, where they meet giant nematodes, mites and protozoans? That would be something. Not that I think it is ever going to happen. It would just be great if something never done before, was made, and in the right way.
