not sure if u and i have the same understanding of what "canon" means.
2nd question:

the film proposes several possibilities, but chose not to answer anything. just like in alien (the 1st film), there are numerous questions that linger around. who or what is the space jockey? where did the xenomorph come from? the hints to those questions only surfaced 40 years later in prometheus. even so, it didnt give any clear definition.

maybe we need to wait another 40 years...

To those who have watched the movie in cinema, any bad editing by our local censorship board? In other words, any scenes got sliced off?

Some people in the cinema went "urgghhhh" during the "operation" scene btw

I honestly don't see any point in attacking him personally like that. Does venting your anger at him via tweeter achieve anything?

Instead of directly insulting people, maybe people would be better served by just expressing their disappointments publicly and hoping the public opinion would convince the producers to make a more sensible story line in the sequel. If they ever green lit one.
