Hell, there is not much beyond three movies worth mentioning so ill just list all Sci-Fi movies worth mentioning in the current decade...
1)Source Code (2011) - 9/10 (my #1 time-travel variation movie straight up)
2)Tron Legacy (2010) - 7.5-8/10 (this is pretty much my #1 PG rated movie (or at least the best PG rated movie in along time as damn near all of the movies worth mentioning in general are either PG-13 or R, pretty much))
3)Ex Machina (2014-2015) - 7-7.5/10 (this was a 7/10 on my first two viewings but on my 3rd one not long ago (Sep 12th 2018) it went up to a 7-7.5/10 which makes it not much outside of my Top 101 movies)
4)Robot & Frank (2012)
5)Edge of Tomorrow (2014) - 7/10
6)Annihilation (2018) - 6-6.5/10
-)In Time (2011)
-)Terminator Genisys (2015)
NOTE: there is more I like but everything above is within my Top 234 movies at the minimum, with the 7's and higher being within my Top 187 movies.
p.s. Annihilation just recently (on Jan 3rd 2019) went up from a 6/10 to a 6-6.5/10 on a re-watch (my 2nd viewing of it total).
