There where some good and many mediocre and some bad X-men movies. Not every Marvel movie is great either. So down the line X-men will likely improve a bit, like Spiderman did with homecoming. Though Deadpool will probably get a total disney overhaul which is a shame. On the other hand Marvel has never been better than under Disney is flag. So it might not be as bad as we fear.
Please excuse my (probally) poor grammar
