Make sure you keep in mind this is a sub 100 million dollar movie and most of the scenes were shot guerrilla style with a team of 4 people. What they achieved with this approach is nothing short of incredible. The CGI pieces got a lot of love because the actual scenery and backgrounds are real and shot on location leaving the budget to be placed on the robots and future tech. I really hope it inspires other filmmakers to try a similar approach. The way the movie is made excuses some of the faults I’ve seen levied online IMO. The movie isn’t perfect but damned impressive.
