I use Concepts a lot. I’m not an artist, but with the tools and great layer support I find it very useful for sketching the layouts I need. This is a very well supported app that is worth checking out.
I'm looking forward to watching this. I'm hoping it is something I can get immersed in and think about what I'm watching. Maybe some of the reviewers were expecting a vapid J. J. Abrams film with lots of lasers, explosions and people performing impossible stunts every few minutes.
