Ah guys...
Movies dont suck compared to the movies made before 2000. Its very easy to explain, the amount and the age of people who actually watched movies has changed. Young kids and less-evolved people go more to the cinema these days. Movie coperations use this, they make quick stupid movies like planes and hercules.
But really, in the past 5 years some really really good movies have been made:
Gravity
12 years a slave
The dark night (rises sucked in my eyes)
Inception
Django unchained (!)
The list goes on and on. Its just that these movies arent classics, but they will be in 10 years.
