The original 'Blade Runner' didn't spend approximately 50% of it's run time "gazing at the scenery" just because Ridley Scott wanted to show off what his effects people could pull off, nor was it "a 1982 thing." It was a deliberate style choice to evoke the even earlier noir genre movies from four decades prior. It's a bleak, sombre world with a beat-up, hard-boiled protagonist in a world consisting mostly of smokey offices, rain drenched streets and chain-smoking femme fatales. The central plot was almost entirely besides the point and indeed, it's so straight forward it could easily be summed up in only a paragraph or two. It's a mood and character piece, and on that score at least, the sequel was quite faithful.
Indeed, I'd go so far as to say that despite what I just said, the sequel injected a *lot* of more modern style action sequences putting it a little closer to the likes of 'Children of Men' than 'Blade Runner'. How many and what kind of action sequences did the original have? Not many and very simple, respectively. Two brief fist fights both concluded with an equally brief shooting, topped off by the final show down that bucks tradition by not bothering with an action climax or victory and simply ends it on a philosophical note in tone with the rest of the movie, followed by an appropriately ambiguous denouement.
Again, I'm not saying you have to like either movie for any of these reasons, but it's unfair to criticise something for not being what it wasn't even trying to be in the first place.
For example, you can fault say...'Robocop 2' for any number of perfectly fair reasons, but one of them is not "didn't work as a romantic comedy", because it never tried to be. To look at the other end of the spectrum, it would be equally ridiculous to complain that 'The Godfather' "didn't have enough laser guns and space aliens".
