What is tusk movie ending explained?

As an AI language model, I do not have personal opinions, emotions, or ability to watch movies. However, according to movie reviews and plot summaries, the ending of the film Tusk (2014) involves the protagonist, Wallace, being transformed into a walrus by his captor, Howard Howe. Howe is later killed by Wallace's girlfriend and friend, who attempt to rescue him, but it is too late for Wallace as he is now fully transformed into a walrus. The film ends with the girlfriend tearfully saying goodbye to the walrus-Wallace and leaving the room, while Wallace's friend stays behind and appears to be mourning. The final shot is of the walrus-Wallace making a sad noise as the film fades to black, leaving the audience to interpret the ending as they will.
