X3 does have some good action moments, but all of them, in my opinion, don't reach the level of the power display Bryan showed in his movies.
Sure, Dark Phoenix is stunning (though I can't get over the fact that we didn't get a Phoenix Rising scene. It was obvious, it was a guarantee of a wonderful piece, it was supposed to be one of the best, most artistic displays of power of the trilogy, but it was a let down, a huge one, a terrible one). The GG Bridge is awesome. But that's pretty much it. Beast kicking those soldiers still doesn't compare to the greatness that was Nightcrawler. Kitty's chase scene is smart on the beginning, and even funny and creative. It almost resembles the way Singer would do an action scene. Although they are beautiful, and bring a tough competition if we had to choose the best, I still think that Bryan, in the mix of everything, nailed the powers better and more beautifully, elegantly.
Ratner, IMO, tends to make their powers seem ordinary, in your words "blending more with the movie", which is something that takes out the superhero feel (imo). I prefer the bursts, the moody display, the fact that the powers are really an extension of their feelings, mostly their anger. The awesome displays interlaced with character moments than to see their powers treated as "common". Reaching this part, we fall in opinion matter. But what I wanted to show is that you can't neglect that, like you or not, prefer you Ratner or Singer, the latter nailed, beautifully, most of the powers, if not all. So we can't say that "Singer nailed the drama, Ratner the action". Singer nailed both, not perfectly, true, but he nailed, most times (and now I fall in opinion again) it better than Ratner, because this one didn't nail the emotion, although having pretty awesome action displays (something that Bryan also hit).
