At least let me see the value proposition directly (not in a screenshot) for one movie/minute before forcing me to sign up.

Is signing up even truly integral to the app in some way, be it functionally or for monetization purposes? Either way, a registration wall during beta for a highly visual product doesn't seem like a great idea.

I know the counter-argument to this is probably that this limits the number of beta users and makes it less overwhelming to manage early on, but I side with the school of thought that favors exposure above all else, especially during early stages.
