To quickly summarize from, "Rising '44: The Battle for Warsaw," by Norman Davies, since I don't have the book with me right now: the Communist Party chose to rewrite history, inflating the contribution of the Armia Ludowa while construing the Armia Krajowa as an insignificant force of reactionaries. The AK was also criticized for starting the uprising, as a greedy mistake the bourgiousie forced upon the Polish people in an attempt to maintain the pre-war status quo. The Home Army leadership was ruthlessly condemned for vesting such destruction on the Polish people, while most AK rank-and-file were rehabilitated after a period of forced labour/re-education (with the exception of the Cursed Soldiers who continued to fight against the Communist authorities.)

IIRC, the first official commemoration of the Rising by Communist authorities took place in 1946, but was specifically dedicated to the fighters of the AL, rather than the AK. A memorial was built to the Ghetto Uprising in 1946, and this is where the famous Warschauer Kneifall happened. The Gloria Victis monument was built at the same time, dedicated to the fighters of the Rising. A 1948 cemetery plaque was erected to the victims of German executions. Other monuments to the Rising were built in the post-Stalinist period, and celebrations were allowed, but were kept small and local. The official monument to the Rising was only completed in 1989. The date of the Rising was only made a holiday in 1991 after the fall of communism.

Discussion of the topic was discouraged for a long time, and it wasn't until the post-Stalinist thaw that Polish culture even started to represent the AK in film, and even then the preferred course was to portray the AK leadership as foolish and vainglorious. The film, "Kanał," is a good example of how the AK had to be portrayed at the time. The soldiers are portrayed as brave and likeable, but the officers and members of the upper class are all either foolishly heroic, bumbling idiots, or mad. The film also contains one of the earliest veiled criticisms of the Soviet (non-)intervention, with the two hero characters resigning themselves to death while looking east over the Vistula.

Literature relating to the Rising was published in the People's Republic, largely starting in the 1950s, but this was confined to memoirs, poetry, and prose dramatization which ignored the role of the Soviets. "Stones for the Barricade," and "Zoska i Parasol," were published in 1957, and are still taught in schools today. Anna Świrszczyńska's, "Building the Barricade," was published in 1978. "Hour W," by Jerzy Stefan Stawiński was published around the same time, and made into a film in 1979.

Public criticism of the Soviet's role was very limited until the fall of the Communist government, but was still held in the public consciousness (just not discussed) in the People's Republic.

Apologies for the hastily written response. I'm in the middle of a move and all of my books are in storage. If you're interested in the topic, I highly reccomend "Rising '44," by Norman Davies. He's probably the best English-language historian on Poland, and the book is rife with his own translations of Polish primary sources. It also goes into the legacy of the Rising, not just an overview of actual events.
