What I have a much bigger problem with is the OP's suggestion that there is something in the film about not being able to beam up when beaming down happens without a hitch! The transporter has never been asymmetric like that. Of course, it could be, and by all rights should be, but it isn't. The transporter room guy needs a clear image of what is at the other end, and if he can't see it well enough to beam it up, he can't send anybody down "blind", either.
Or can he? The issue has never arisen in previous Trek, because no beam-down has been desperate enough. Desperation has only involved getting a hero out of a jam, and generally this can't be achieved by sending more people into said jam. But this scene might well involve something worth risking a "blind beam-down".
...Apparently, the hero beaming down isn't able to pack a beacon that would allow him and his target to subsequently be beamed up. But that sort of a limitation can probably easily be handwaved away.
Dunno. Gonna see the flick no matter what. Sounds a bit silly in places, but probably not too damningly so.
Yes, at a critical moment we find that you cannot beam an object up but you can beam an object down right next to it
My advice is to try your best not to focus on Trek Tech or plot because it makes little sense (IMHO!) just enjoy the spectacle and the performances of the cast because both are A+
The tech and plot issues are probably no 'worse' than what occurred in Star Trek (2009). The trouble is the novelty has worn off and it has to live or die by its plot which comes under more scrutiny and falls to bits as a result... again... IMO.
