Being the fourth book I've read of Sinclair Lewis', I was initially primed to be thoroughly impressed by this novel. After all, it's widely regarded as his best and most-read work. However, to my honest dismay, it has turned out to be my least favorite among his books so far. The main reason for this lies in the title character himself, Martin Arrowsmith. He is, without a doubt, the least comical protagonist I've encountered in Lewis' works thus far. In this regard, a significant portion of the satire seems to be lost, as his central figure is neither a buffoon nor does he harbor outrageous delusions of grandeur. Instead, in many respects (except for the ending), Arrowsmith is a truly admirable character, wholeheartedly striving to adhere to his beliefs and resist corruption. In every way, he's not the kind of character I would have anticipated from Sinclair Lewis, and in this instance, that's a drawback. I hardly laughed at all while reading it.
That's not to suggest that Lewis is only effective when he showcases his biting, acerbic wit in character portrayal. But since this novel leans less towards a character study and more towards an actual story, it somewhat threw me off balance. In the end, I wasn't entirely impressed. Given the abundance of science involved, I'm certain this was an extremely important and relevant novel in its time. However, today, it doesn't really strike me as all that remarkable. This is often the case when something new and innovative is introduced. Over the years, so many others build upon it and make it their own, to the extent that it begins to feel tired and unoriginal, even though it's the original masterpiece. For this reason, I find Arrowsmith a bit lackluster. It's most definitely a well-written novel, but it wasn't what I expected, nor did it pleasantly surprise me. In the final analysis, it's just "Meh" for me.
