After you have watched despicable me series, you definitely would have expected a lot from the movie minions, but definitely it did not stand upto the mark of the standard set by previous movies of the franchise.
The plot was below par, not at all interesting, totally irritating, annoying& boring, only people who watched the full movie in the hope of some surprise could tell you how disappointing the movie was, really it was way too disappointing to withstand watching the movie.
