I'd give it a 6 or 7. The humor and some of the action was great, but coming from someone who has never read a comic in my life--and already knowing full well what the Mandarin "twist" was at the end because a friend told me--I STILL found his portrayal (or lack thereof) to be so asinine as to be borderline retarded. I knew about his backstory, how he's Iron Man's Joker in the comics, and all of the trailers built him up as this really badass menace who could get to Stark even in his own home. And then the movie itself had this really effective way of not showing the Mandarin in anything beyond a shaky cam found-footage style. Everyone just talked about him, how afraid they were of him. But all of this amounted to nothing more than an awkward joke; the trailers and marketing were bordering on false-advertising really. It's the first MCU movie that really made me hate it; they've had some "just okay" films in the past, but overall its a great series. But they generally treat their characters with more respect than this. Other than the humor, it all came off more as an "old Marvel" movie, or old comic book movie. Like it was just going through the paces without trying to be interesting. IMO it doesn't live up to the MCU's standards.
