The basic story is quite similar though - a spaceship, here not so big, and with only a few people on board, searching for the last resort of mankind, while earth herself is nearly destroyed. The main difference to 'Sunshine' and 'Pandorum' is the amount of bloodshed, and also the budget, which was approx. a tenth of each of the former's.
It may be true that the first 40 minutes are a bit hard to overcome for the average sf-action lover. There we learn to know the crew, which is a bit of a family since they are now together for seven years, as we are told. The movie takes it's time to establish a certain mood of day-life, instead of bringing up severe conflicts or delusions and problems immediately. That's OK, if you ask me, I do sometimes like a more lifelike approach. And who, when not astronauts, should be able to live through such a long journey?
When the ship encounters the derelict ship, as described in the story-line, the movie gains momentum as it should, and it doesn't lose it until the end, providing enough tension and action for a rainy evening in front of the flat-screen. Acting is solid, directing and special effects are OK for a Direct-to-Video or Video-On-Demand production (which I assume it is).
As the budget may dictate, 'The last scout' cannot claim to be special or outstanding, like said examples, and it doesn't want to. Instead, it tells its story, and this is where it looses some stars, the story ingredients are too much copied from those other movies, minus a certain amount of their violence, to be suitable for families, I think. It would have taken only a bit of time to form a more creative and interesting solution within the premises, at least avoiding said big models. So, for the SF veteran, the outcome and the explanations toward the end are a bit disappointing.
I can give the movie yet 610, as 5 would be too low in my eyes.
