Saw it last week and found it extremely dull and quite empty. I adore D9 and found Elysium to be very, very entertaining.
Chappie came across as a stretched out Die Antwoord video clip combined with a Sony commercial. There were hints of a more thought out movie in there during certain scenes, but the constant, blatant product placement and the horrid performances by Die Antwoord combined with a paperthin script made me cringe more than I enjoyed myself.
What the fuck was Sigourney Weaver doing in this movie, except for cashing in? She's got, like, 5 lines total. And let's not talk about Hugh Jackman's character. The guy was given fuck all to work with. Terrible dialogue and very little convincing motive.
Sharlto Copley was great as Chappie though. A pretty emotional performance brought down by terrible writing. (Gotta say, Die Antwoord's music, and even more so, attitude just don't jive with me, so this last remark might be a tad too personal to objectively judge Copley's performance. )
Loved watching Yolandi, no thanks to her acting, but she's just a very pretty lady.
Ohyeah, the ending made me want to throw my boot at the screen. What. The. Fuck.
Please Blomkamp, you are a very talented individual, don't fuck up your Alien project.
