I've been singing the praises of the inbetweeners to all and sundry since I watched it first time round. A truly wonderous comedy with brilliant actors and incredibly well written.
The theme park episode is superb. When Will callls the front row of disabled roller coaster passengers absolute arseholes! Genius
As I said on a previous post. If you're male and can remember your teens, you'll love it!
Series 1 on DVD is only £7 on play atm.
edit: and as peep show has been mentioned, series 1-5 also on Play for £16 ish if I remember rightly.
Getting both come pay-day
