Is Gatsby Heroic?

Throughout the novel Gatsby's mind is very far from reality as he thinks about his dreams and aspirations. As Megan mentioned, Gatsby never sees Daisy's faults and her shallow nature. However, I cannot help but admire Gatsby even though he is so distant from what is happening.
Towards the end of the novel Gatsby's true heroic nature comes to light when he is waiting outside of the Buchanan's home right after Daisy had hit Myrtle Wilson with his car. While Gatsby and Nick are talking, Nick asks "Was Daisy driving" to which Gatsby replies "Yes...but of course I'll say I was" (143). Gatsby would do anything for Daisy and he proves this again and again throughout the novel. In this same scene Gatsby waits outside to make sure that Tom will not harm Daisy. Nick asks "How long are you going to wait?" and Gatsby replies "All night, if necessary" (144). Despite the fact that Gatsby is essentially "watching over nothing" the reader cannot help but admire Gatsby's unfailing love.
