I spent some time messing around with a new account on the tier on Thursday, and while the experience of using Netflix was mostly the same, what struck me was the unpredictability of how many ads I’d have to watch.Here are a few of the variations I experienced:- Every Netflix-branded show or movie I tried had an ad at the front but had differing numbers of midroll ads- Community, Seinfeld, and Grey’s Anatomy had no ads- Three Netflix movies I tried only had ads at the beginning but none in the middle- The movie Crazy, Stupid, Love had front ads and one spot for midroll ads- The Italian Job had front ads and three spots for midroll ads- Spider-Man had no adsAs for the ads themselves, they’re pretty standard online video ads.On the web, Netflix will helpfully take you to a new screen that lets you immediately upgrade to a higher-priced tier with access to everything.And I saw a bunch of padlocks in search results for “classic movies” like Skyfall, 28 Days, and The Imitation Game.If that’s something you can live with, and you’re okay with other tradeoffs like 720p video quality and no offline downloads, then saving a couple of bucks with the cheaper tier might be worth it."
