Well, one can of course accomplish different effects by something like the panel above. Instead of getting a full page or more of fairly graphic violence (I'd say) the storyteller (it is JB isn't it) can get around that and move the narrative along (while still having the event). Is it effective in this case? I can't say without getting the rest of it (where is it from btw).
And as for "showing not telling" (which I guess applies to film as well). The spoken or written word should not be seen as something necessarily evil. It's up to how it is done, and if it's effective storytelling in that specific case.
IMHO

I know there's no "guessing", I was merely trying to humble about it.
I just also happen to think that it shouldn't be forgotten that film isn't only visual, but audiovisual, in the same manner that comics have the full use of textual language. Thus while showing rather than telling might be a good rule of thumb if one is teaching writing for visual media 101, I think that constructive use of language (audio or textual) can be equally effective in the right places.

And the image above is, of course, apart from verbal storytelling a reaction shot which does show us quite a bit as well, methinks.

AWC rules! I bought the JB trade when it was released and just pray that Marvel will eventually be intelligent enough to release the rest of his run (and why not some of his Avengers while they're at it).

Let me add my new piece to the mix......from the 1991 Marvel Trading card set.

those are sweet, Abraham!  Where did you get those?
