Interstellar is a great idea for a movie but it is riddled with plot holes which ultimately overwhelm it. Having said that I did enjoy it, particularly the robots.
On the other hand I saw Fast & Furious 7 at the weekend.
Perfect Friday night movie: pretty much nothing but action from beginning to end. If you need to de-stress at the end of this week go see it. Just sit back and unplug your brain for a couple of hours. Bliss
