I wouldn't go so far as to call it a killer. I've used it as an alternate streaming source for a long time (its integrated into most sony streaming media boxes) with few issues.
The movie selection is a very small set of older movies (from the 80s to 90s) that is rarely repopulated and paid for via annoying ads every 15 minutes or so. But if you like watching some of the older flicks, it's great ( Cronenberg video drome, etc). So that's more of a third tier movie audience.
Netflix is more 2nd tier (along with Amazon, who is the greater threat) or older releases, with a slightly higher re-population rate of films/tv shows worth watching.
Redbox, DvDExtreme, etc.. cater to the newer blockbuster audience with a slight premium (~$1-$1.50) and the cost of travelling to a kiosk, whereas the plethora of streaming sites with new blockbuster releases still charge an arm and a leg (around $5) per film. When someone comes up with a model for NEW streaming blockbusters at $2, then I'd be more worried about the kiosks disappearing or Netflix/Amazon losing customers and margins.
