Avoid like the plague.
Just wanted to write a quick warning, so that you won't be deceived by the hype here, so far. On its favour, I can state the sensibility displayed and the noble cause. And, being a Lisboner myself, it is obviously a very beautiful, soulful and picturesque place to film. Nevertheless, the cinematographer Adam Bajerski did a very interesting job.
OK, that's mostly it. The acting is terrifyingly dull. Starting right with the main actor - I mean, this guy couldn't act if his life depended on it. Cringeworthy. Alexandra Lara, while far from a top-class performer, shows more than enough chops when rightly directed (vide the superb Control). Not the case here. Of course the campy, rather pedestrian dialogue never helps. And its delivery feels ever so awkward, not for once natural or credible. People just don't talk like that. I don't even want to dwell much on the script problems, but why the hell would English, french (and even a German ex-pat) blind children be doing on such a far from luxurious institution in Lisbon? Certainly all the sun and light are not the best treatment for the blind-eye - probably explaining the high blindness rates. You'll very often find yourself bumping into a blind person, whilst walking the streets of Lisbon.
To sum things up, in the hands of the right director this could have definitely been something. Keeping the moody slow rhythm and attention to sounds, but being more demanding with the extras and supporting actors. Even Ian's darker side should have been more wisely explored. Instead you are left with a slow movie, going nowhere, with a somewhat ridiculous script and with weakly handled tension scenes. You'd be better off driving that same 28 tram at the end of the movie and visiting a city far more interesting that its all-too-scenic display.
