3) Take Some Time
There are definite signs of fatigue from both cast and crew in X-Men: Apocalypse. The cast, returning so soon after Days of Future Past, seem either bored or in a constant struggle to lend some life to their characters, characters that are frankly flatly written by Simon Kinberg. Perhaps understandably so: Kinberg had hardly any time at all to prepare Apocalypse, and neither did Bryan Singer. It shows, too – the film feels rushed, an opportunistic product made to cash in on the success of Days.
Obviously it would be better for everyone if there was more time spent preparing the next one. Apocalypse has been received generally with a shrug by both critics and audiences, with the focus of the ire being how hollow and inessential the film seems. No movie should go to shooting until all the pieces are comfortably in place beforehand. A bit of extra prep for X-Men: The 90s wouldn’t go amiss, at the very least to ensure the screenplay doesn’t again read like a first draft.
