I like science fiction movie, especially related to time travelling. Watched Project Almanac (2015), and there are quite a lot of interesting points.

[WARNING! CONTAINS SPOILERS]

Firstly, unlike Back to the Future (1985), time travellers going back will not meet the time travellers selves, this can be seen when the protagonist and the friends solve Quinn’s chemistry problem. Secondly, unlike Time Traveler’s Wife (2009), travelling to the past can change the future; yet in Time Traveler’s Wife the timeline is fixed, there is only one, single, timeline.
