A box set is basically the entire series – it's becoming a bit of an anachronism in the era of streaming since people tend not to acquire a physical 'box set' but as we know MLIR. Once suitably equipped with a box set, the option to binge-watch becomes available. Reminder those days when you had to be ready at 9am on a Thursday night to watch the series of your choice (to be honest, I don't) – now you just cue it up whenever it suits. And well, you've watched one episode and it's midnight, but oh, another episode, go on, the morning isn't for ages. Another episode? Come on, who needs more than 4 hours sleep?
Alias is on actual DVD, I had to find the remote control. It's blimeyly old (2001!) and Bradley Cooper looks about 10. It's quite dangerously addictive as every episode ends on a cliffhanger (and it's so old, I can't usually remember the details from when I first watched). Is Vaughan drownded? OMG Sydney's mum! Sloan, you big murdering meany. What the hell is the big red thing for? Alas, the need to sleep left those questions unanswered...
