I have always maintained that I like watching Steven fighting. That he's not doing the kind of bone-breaking fight scenes that he used to does not bother me one bit (I spent most of the fights scenes in Marked for Death with my eyes shut because they were too much, even for me). I was quite pleased with the fights in The Foreigner, less pleased with those in HPD because I knew he didn't do most of them.
Let's face it, a bad guy who gets a slap from someone Steven's size is going to be hurting, any way you look at it.
The reality is, Steven is getting old; there are going to be fewer kick-a** fight scenes with him doing all of the work, regardless of his size. So there's going to be more drama than action in his films - there's going to be fewer bones broken, because he can't do it anymore (size, age, whatever) - or maybe because he *won't* do it, for whatever reason.
The expectation that he's going to do exactly the same thing now as what he did 16 years ago is entirely unreasonable. The straight up 'action' film (those that don't depend on wires) is pretty much a dead genre, these days, and good directors for such films are few and far between. Clearly, no one - or, hardly anyone - in the US film industry wants to work with Steven any more, either, so he has to go overseas, and work with no-name (well, no-name in North America, his first audience) actors and directors.
Do I expect the same kind of action now as his first four films? No. Do I expect him to play the same kind of character as he did in his first four films? No. Would I like to see more of his old-style kick-a** action? Sure I would - but evolved, maybe, to what he is today, rather than try to do what he did 16 years ago when he was younger and lighter. But I'm not going to moan about the "good old days" if I don't get it.
And yes, I confess, I find him easy on the eyes, and I like to look at him, but I like his fight moves, too, and I like the way he executes his blows, making them look so effortless and casual, 'en passant' almost. Do I find his recent fight scenes disappointing? A little, mostly because he's too busy trying to be coy about his weight. I suspect if he stopped being so coy about it, we'd see more of the good stuff.
