I usually don't mind, but tend to split reviews into two types. Either I understand the context and can quickly do an in depth review, or I have to take some time to actually learn about the code by reviewing the surrounding systems, experimenting with it, etc. But in both cases I would at least run the code and verify correctness.

I think it becomes a chore when there are too many trivial mistakes, and you feel like your time would have been better spent writing it yourself. As models and agent frameworks improve I see this happening less and less.
