Just way too implausible
It was cool to get back out to a movie theater after well over a year, but the movie itself was just too outlandish and cheesy, even though Bob Odenkirk was charming as ever.
I mean, I don’t demand strict realism in my violent entertainment (I loved THE AMERICANS and FARGO on FX, and BREAKING BAD and BETTER CALL SAUL on AMC), but this was a bridge or two too far. If one guy is going to take on an army, I need him to have a radioactive spider bite, or high tech armor, or something. (If “Nobody” had been in the Afghani cave instead of Tony Stark, he could have skipped the surreptitious armor construction and taken out those terrorists with his bare hands!)
