"Must see" in this case depends on what you mean by must. If it means "boy, you're absolutely going to want to see it no matter whether you're a casual movie goer or a film fanatic," then we're talking All Quiet On The Western Front and possibly nothing else. It's not just an intense, insightful and historically important movie, it's also one of the most entertaining and watchable movies of the entire era. I've written about it at length here, here and here.
If, on the other hand, by "must see" you mean "what you'll need to see to get a real sense of this moment in movie history and prepare you for what comes next," then I'd say the movies on the above list would do you.

After that there are a handful of movies I'd give thumbs up to without necessarily calling them essential.
Anna Christie, Bulldog Drummond and The Love Parade I've written about, although in the case of the latter, not extensively. Judging by my readers' reaction to Maurice Chevalier, perhaps that's a good thing.



You might also check out The Virginian, Gary Cooper's first talkie (which gave us the oft-misquoted line, "If you're going to call me that, smile!"), and Rouben Mamoulian's Applause, starring Helen Morgan as a stripper who reunites with her convent-raised daughter.
And finally, you may recall that I mentioned Man With The Movie Camera during my two-part discussion of the avant garde movies of the late 1920s. This experiment in film editing by Russian Dziga Vertov is highly regarded by some, including Roger Ebert. Not by me, though.
One problem with following the split-year format the Academy used for the first six years it handed out Oscars is that it obscures the fact that between the release of The Jazz Singer on October 6, 1927, and the premiere of Frankenstein on November 21, 1931, Hollywood only produced one truly great talking picture, and that was All Quiet On The Western Front. Everything else I've written about so far is either silent, foreign or flawed.
The next set of awards won't change things much—1930-31 pretty much shakes out as a three-way slugfest between Charles Chaplin's silent masterpiece City Lights and two foreign-language films, M, Fritz Lang's portrait of a serial killer, and Le Million, René Clair's delightful musical comedy—but at least the stars who eventually gave us the great movies of the Early Sound Era (Cagney, Robinson, Gable, Crawford, Stanwyck, Blondell, etc.) finally make their mark.
I, for one, am ready.
