"Post regeneration" stories have often been a tad "ungrounded" as the newest lead is trying to find his "mark".  As for the "confusion" that takes away time from a more focused performance, has everyone forgotten David Tennant's Doctor effectively "slept" for more than half the episode?  At least Capaldi was conscious most of the time and even when he was sleeping, he was talking, "translating" the dino's bellows and roars, getting us to pity the poor beast.

Of course, I'll take just about any DW I'm offered, even if some might not consider it the most stellar material.  I went through some major Doctor Who withdrawal from 1990 to 2005, with only that single glimmering moment of hope in 1996 when Paul McGann piloted the TARDIS.  Those were the "dark times".  ;-)  I was even grateful for "Scream of the Shalka" with Richard E. Grant's Doctor sporting the Aeon Flux hairdo!  (What were the illustrators thinking when they drew that?!)

I tend to just "absorb" the material and process later after I've seen several episodes.

Anyway, to "bridge" the discussion with Poser, here's a render comparing three different police box meshes, Mick Imrie's on the right, Becco_UK's version in the middle and BoardMan's interpretation on the left.  Boardman's is actually the closest to the real life "Mark II Metropolitan Police Public Call Box".  It had a taller, slightly more angled roof with a larger signal lamp.  The other two are based more upon the  prop from the "classic" series.  The first box was supposedly built with those proportions so it could more easily fit throuh the studio doors.  Subsequent props continued those slightly squat proportions.  The roof of the prop used in the later Pertwee and earlier Tom Baker serial had an almost flat roof, one barely rising above the banner signs.  The props used since the series' revival all have a somewhat taller roof harkening to the real world boxes, but conversely, the recessed paneling (and thus the windows) are considerably more "square" rather than upright rectangles.

 

The "MindRobber" site has an in depth analysis about both real life police boxes and the props used in the BBC series.  You can read about it here...

He even presents a "line up" of the various props, comparing them to each other as well to the "real thing".  Fascinating stuff.
