I just got back from seeing the movie at the lowest price possible, and...
Well for the most part the movie looked really good. The CGI was decent, the lighting was great, and there was some really good shot composition. Tom Hardy played his role especially well and as pointed out, there's an amusing relationship between Eddie and Venom.
Now, you can't run from the bad aspects. There's a lot of cringey dialogue and while plot overall makes sense and was actually paced pretty well, a lot of what is said is laughable and kinda lame. Some of the effects look bad. The main villain probably takes the cake for bad dialogue and I'm also not sure how Eddie Brock is respected as a journalist.
So if you don't take it too seriously I think you'll be impressed that it's not nearly as bad as you were expecting it to be. It's not amazing, it's not terrible, but it is fun. It's hilarious, intentionally and unintentionally. And I definitely would watch it again, especially with friends.
