Why didn't the general audience engage with X-Men Apocalypse

I actually kind of wish they had held back on Magneto. Either have him make a surprise appearance towards at the end of the movie agasint Apocaylpse or have his whereabouts be a mystery. We already had five X-Men movies where he featured and it would have been a nice tease for the audience.

I can't help but wonder if it's the that Apocalypse doesn't have the same pathos as the previous films are. It's there, but more subduded and it's defiantly more an adventure film then the previous.

Haven’t ALL of the X-Men films made money?  Even the ones which are generally not popular, like X-Men: the Last Stand and X-Men Origins: Wolverine?  

I’ve loved them all—including X-Men: Apocalypse.  I know I’m in the minority.  But despite my feelings and what the critics have said, I don’t know the answer to your question.  If I had to guess, I’d say that perhaps the average fanboy was put off by the changes (from the comic) to the big villain Apocalypse.  I’ve heard some diehards say that he didn’t come off as the same villain that fans were familiar with.  Also, Mystique has become completely different, perhaps due to Jennifer Lawrence’s meteoric rise to super-stardom—they’ve wanted to give her character more to do.  Finally, the timeline could be criticized for jumping forward about a decade, and no one has aged.  

To me, these are small matters and detract nothing from the fun I had watching this.  No, it’s no Deadpool, X-Men: Days of Future Past, or Logan.  But overall, I think the general audience has been too hard on it.
