Have you seen the movie Europa Report? I don't want to spoil any part of it for you, but it's really good. If you have Netflix, it's on there.

Is it realistic or do they find aliens/god?

[SPOILERS] There are some Hollywood embellishments I didn't care for, but I would say the movie is still a lot more realistic than 95% of sci-fi movies. It's definitely worth seeing. In the end, they do find complex life, but no "aliens" like you'd find in a typical sci-fi action movie.

aliens. Btw, I find the movie horrible...

Race to Mars, a 4-part miniseries by the Discovery Channel, is also worth while. The spacecraft and lander are based on existing ideas for trips to Mars. The physics in it are depicted accurately, as far as I could tell. Problems that arise seemed plausible, too. The interactions of the crew are well done, and aren't hammed up for dramatic effect.

> it's really good

No it's not.

The acting, story, soundtrack and effects all seemed good to me. What didn't you like about it?

I liked everything but the "documentary" aspect. Too many flashbacks/flashforwards, needlessly restrictive camera angles, pointless exposition, and it was really easy to lose track of the chronology. They even reveal one of the crewmember deaths before you have a chance to meet the guy, then they jump straight to his death, which was supposed to be a pivotally emotional moment for the crew but you haven't had a chance to care yet.

I don't regret watching it, I think it was a decent film overall, but it needed a different director.

I agree. Everything was good until the guy who wanted to show off his After Effects skills got to it. But even that wasn't enough to prevent me from enjoying the movie.
