I certainly don't think he should stop making films. The films themselves are extremely well made. Sets, production, music, location, world building - the lot really. The only weakness is the script. He's a very good director, they just need to put their scripts through the common sense box.
Saw Charles Dance once say about scripts, you can't make a silk purse out of a sow's ear.
That's true actually. Very easy to get swept up in all the 'hack' director chat. He's still, for the most part, a superb Director. He's banked enough good will for the rest of time imo with Alien and Bladerunner, so...
