Is Circles of Four a good starting point to start reading Venom?

Personally i havn't read that much of circle of four, but that's because i much prefer the old look of the venom symbiote where Eddie Brock is its main host, i prefer brock as the host, i have to say. But i suppose its personal preference? Maybe read into the hosts of Venom and see which one intrigues you the most and go from there? The very first host was Spider-man, and then it went to Eddie Brock, reading into the more past areas of the symbiote is very interesting i must say, because Eddie brock soon doesnt want to be the host and thus in a nutshell later anti venom is created. But personally id start from the beginning, but it depends on your personal preference. Any questions, just ask and i'll try my best to answer them :D

I'd recommend just reading all of the series that just ended. Was good stuff
