Were we watching the same episode? The psychic opened the portal, but couldn't keep it open long enough to get the time-traveller AND the Doctor out. Thus the TARDIS and Clara to the rescue. Second time around, the psychic opened the portal to drop the Doctor in and give him time to locate the monster, then the TARDIS swooped in to pick them up. Admittedly the TARDIS might've been unnecessary the second time, but at least they knew it would work that time.
Yup. That would be another explanation that might have worked in an episode that was better written: The TARDIS can get in-and-out fast enough because all it's doing is picking up the Doctor (whereas if it had to drop him off, wait for him to locate the alien/Hila, and then leave it would take too long). It's got some problems (why can't the TARDIS drop him off, leave, then come back and pick him up?), but it would at least provide a functional explanation.
Unfortunately, it doesn't actually work in the episode-as-poorly-written: Before the situation is just "pick the Doctor up", we're told the TARDIS can't do it because of X. After the situation has become "just pick the Doctor up", we're told that the TARDIS can't do it for the
exact same reason. Then Clara calls the TARDIS a cow and suddenly the reason no longer applies.
The only explanation I can think of is that it's maybe a dialect thing - you're in the US? Maybe you guys found it a bit harder to catch what they were saying (they do speak fast), but it was pretty clear to me. It was very explicit that it was a "we can go in for only a few seconds" thing, and very explicity not a "we can't go in at all" thing.
I understood the line of dialogue. It's still bad writing.
I think the importance of the psychic link in the TARDIS trips is being underestimated. Note that, while the TARDIS makes its own way into the pocket universe, when it emerges it materialises within the portal that the psychic link was opening.
That's my personal fan-wank.
As I mentioned before, there are a lot of explanations which would have worked within the structure of the episode with only minor changes. Which is why it's so terribly unforgivable that the episode was so poorly written as to not include any of them.
And because this post hasn't gone on long enough: any critique of the writing in Hide that doesn't favorably mention the real heart of the episode --ie, where it stops being a period ghost story and becomes a brief history of the Earth's whole history-- and the lovely, affecting lines given to Clara (and the Doctor's fumbling response) is lacking in the worthwhile criticism department!
It's a decent couple of lines, but it's not explored in any meaningful depth. It's also flawed by the fact that the entire sequence is another example of the episode breaking its own rules: You can only photograph the ghost if the psychic is present. The Doctor leaves the psychic behind and continues photographing the ghost.
Cut the line that establishes that rule. Or bring the psychic with. Or have the doctor apply a filter to the camera. (The filter could even be the blue gemstone that's used as part of the seance.)
This is the most frustrating thing about the bad writing this season: Most of it would be really trivial to fix. There's simply no excuse for the scripts to be this sloppy or the conclusion to be this weak.
