Do we really want a Mad Max 4? (spoilers for 1, 2 and 3)

According to the IMDb, Mad Max 4 is in the works. While I loved the first two movies in the series (especially the second one), I thought the third one was kind of pointless, and I don’t really see the necessity for a fourth part.

The first two movies work. In the first one, Max is shattered and becomes a destroyed man. In the second one, he rises up and becomes a human again. I think the Feral Kid sums it up perfectly:

After this, did we really want another part? And yet it came, and eighteen years have passed since. Isn’t it time to lay this to rest now?

Then again, there is one really cool aspect they could pursue with the fourth movie. Mad Max is quite unique in that there is a substantial change in its background world between the movies, and that is hardly addressed at all. In the first movie, society is breaking down, but it is still functional. In the second, the apocalypse has happened, but we never see exactly how. It’s a moot point: society has collapsed. What they could do in the fourth movie is rebuild society, show how humanity rises back up. We know the Feral Kid survived until old age and remembered the time of the black fuel while few others did; perhaps we could get to see the new society, adapted to the new circumstances? The cheesy part of me would like to see an old, settled-down Max, perhaps as protector to a small village, telling tales of his younger years to the kids.

But I’m not sure that would work, and maybe we’re better off never seeing the fourth part. What do other Mad Max fans (I’m sure there are a few here) think?
