The fight was a little underwhelming honestly

In the novel, it was a bit more intense

A little bit, yeah--Kind of similar to the ending of Stranger Things. But, since this is a comic drawn panel by panel, there is only so much an artist is willing to take the time to draw, so I don't blame them completely tbh ¯_(ツ)_/¯

I think they drew, what could be considered, the most prominent moments from the novel...I assume, anyway.
