1. The Adaptable Sentinels - X-Men: Days Of Future Past
In Singer's return to X-form, the dystopian future timeline is presented as a product of the timeline in which Mystique was captured and mined for her abilities, which allowed Trask to develop his new sentinels with their shape-shifting abilities taken from her mutation. That's all fair enough, though clearly Mystique couldn't just become a teapot if she wanted to, but there's some allowance for creative licence. What doesn't work is the fact that the sentinels appear to have learned a different mutant's abilities from her as well. Rather than just being able to adapt their shape, the key to the sentinel's power and devastating impact is apparently their ability to steal powers from mutants they come into contact with. Which basically makes them Rogue, not Mystique. Yes the extended scenes suggest that Rogue was imprisoned, and could have been used to help build the sentinels, but she's not dead like the other mutants who had their mutations stolen (including Mystique) and it's too much of a reach to suggest that the sentinels learned that from Rogue much later when they were already dominant, when their adaptability is suggested as the key to their successes.
