after skimming the 14 minute video of inside Europa One and outside the ship it really looks very realistic the production design/art direction inside.
Look at this tour of the International Space Station and it looks familiar:
International Space Station Tour 2012 (HD) ISS Tour
it is 55 minutes!
While Europa Report
looks a little stylized like Moon (2009) inside the Europa One ship really reminds me of the production design on the ship Antares
