I well say, I agree on Hush if you've only read Hush. If you haven't read Heart of Hush, then I completely disagree. I say this because Heart of Hush is a great sequel to Hush that adds to Hush's backstory and makes you love him.
You get to explore Hush's relationship with his mother. One of the reason he hates Bruce Wayne is because of his mother. His mother always compared him to Bruce. His mother always praised Bruce while putting Tommy down. Tommy even skipped college to stay home and take care of his mother (yea I know he tried killing her but still). When Tommy meets a girl who's the daughter to a crime lord in Gotham (it's just a coincidence and has nothing to do with Tommy seeing her) , Tommy's mother cuts him out of the will. Because of that Tommy kills his mother and goes to become a surgeon. I love how Thomas's relationship with his parents is just the opposite of Bruce and how he and Bruce were best friends. Strongly suggest you read Heart of Hush.
Best part of Heart of Hush is Hush's plan against Bruce. He together with Mr Freeze (Freeze never talked just a cameo) found out a way to remove the human heart out of a person while keeping the person alive. Hush also performed plastic surgery on his face to look like Bruce Wayne. He together with Scarecrow sets a trap for Batman in which basically Bats fights Crane and Hush finds Selina, attacks her, and removes her heart hurting Bruce in the worse way possible.
It's a great sequel. Smaller then Hush but just as powerful. Paul Dini really improved on Hush in that, Hush Money, and House of Hush. Hush is definitely a better character then Eddie Brock's Venom.
