I don't have a menu. I just have several rows of "covers" to scroll through and I press the triangle-button to get the search feature up.
There are as many as 6 different UIs out there, depending on which device you use. The PS3 changed the first week of Feburary from a sleek well organized easy to use UI to a more limited, less intuitive version that seems to be universally despised across the internet. Screenshots of the various apps can be seen here-
The good PS3 app-

In the last link, the poster details how he got his UI to change, but others trying the procedure didn't get an alternate...and the 'Russian Roulette' nature of it may yield a version of the app you
don't like. So, take care should you want to try and make a change.
The multiple UIs aside, NF Watch Instantly has been a great value to me. I've gained access to British shows I've never heard of, and others I simply wouldn't have take up space in the disc queue to try out. They have deals with pay tv channels Starz and the newer Epix (owned by Paramount/Viacom, MGM, & Lionsgate) which provides them with more recent theatricals. Warner Bros head Jeff Bewkes has engaged in a hostile, one sided, war of words with Netflix, with the intent of making it harder-and more expensive for NF to acquire recent Time Warner owned programming, seeing the outfit a threat to corporate siblings HBO and T-W Cable. But even with older Waner titles, the NF streaming library still offers tremendous choices...
The most important thing that newcomers should bear in mind is that the streaming service ought not to be considered a substitute for a cable or satellite subscription. There's been some harsh reviews on the web by some bloggers who look at the selection offered and raise their noses at it, expecting Inception and other movies fresh out of theaters. That's not gonna happen as the major studios withhold those for pay per view and VOD, where they get a slice of the rental pie.
Treated as a supplement to whatever you have now, Watch Instant is an affordable addition to your entertainment options.

In an unusual development, this site is far better than Netflix's own, it offers box cover views, genre submenus that can be further filtered for tv or movie only, new arrivals and what's about to expire. Give it a look.
