I was not impressed with the movie, I felt it was a one sided tale told ignoring so many variables. Running for 132 minutes which is a little over two hours, I felt that the movie lagged in some parts. I was somehow taken aback, shocked, and a bit heartbroken about the ending.

I was, on the other side impressed by the intense performance of Cooper who in my humble opinion keeps upping his performance one movie at a time.
I did feel that the movie missed the realistic feel of being at war, It portrayed a single point of view which advocated why America needed to go to war.

I also felt that it is heavily promoting violence from the very first lines of the movie even before it turned into a war movie.. I was not impressed by the story line and I feel there are many movies out there which portrayed a more honest and realistic view about how and why wars are being fought.

American Sniper was surrounded by Controversies since it's release..

The American-Arab Anti-Discrimination Committee said that the release of the movie coincided with increased threats against Arabs and Muslims.

It and others have also accused Eastwood of dishonestly linking the September 11 attacks with Iraq.
Matt Taibbi (American author and journalist) criticized American Sniper for its portrayal of politics. Chris Hedges (American journalist and activist) criticized the film for lionizing the gun culture and promoting the blind adoration of the military.
Zaid Jilani (American blogger and campaigner for the Progressive Change Campaign Committee (PCCC)) said in Salon, quoting Kyle's autobiography, argued that both the film and Kyle's reputation "are all built on a set of half-truths, myths and outright lies.
