If you want some Brock, >>937913 is right.
Tsunami Venom is fucking awful and a good laugh. After that there's The Hunger where Brock gets the whole cancer thing going, followed by Marvel Knights Spider-Man, with some mobster boss' son becoming Venom II. It ends with Mac Garagan becoming Venom III.
Honestly though, Scorpion Venom isn't too interesting and they devolved the symbiote and "Venom" to being a generic monster the size of a building. His only interesting arc is Sinister Spider-Man, but even that's eh.
There's Venom: Dark Origin that tells Eddie's origins and fills in some gaps in ASM 300.
New Ways to Die is the return of Eddie as Anti-Venom, with him getting a mini-series with the Punisher afterwards. Spider-Island is okay if just for Venom, but it's a Slott story so…
Flash Venom is a pretty good read, especially when he gets to Philly. Alongside that is Thunderbolts 2013, adding some more development into Flash and ending with him joining the GotG.
GotG Venom sucks, and Bendis forever ruined the symbiote lore with his Klyntar bullshit.
Venom Space Knight is passable, but everything was done better with Agent Venom's solo.
Lee Price Venom is garbage.
Venom's current is decent, Venomverse is trash.
