Fujicolor Superia 400 (135, 36exp, 400ISO)
Since Fuji killed off Superia 800 and Press 800 (and Super-G 800 whilst we're on this topic) this has been my go to film. Cheap so you can shoot more and stupidly reliable. Once you know what you got, you'll get it each and every time. If you don't it's your fault, not Fuji's.
Here is what Fuji say about it:
An all-round general purpose, high-performance, high speed color negative film delivering truly fine-grain. Superb for snapshots or action, in low light with flash, outdoors or indoors. Ideal for general use with compact zoom lens cameras.
(obviously a company of few words!)
