It depends on at least some degree on the workflow that you want to use. If you just shoot the film, than scan to digital, and print digitally, then you have a lot of control over saturation, etc. If you are staying strictly old school, ie., printing from your negs optically through an enlarger, film choice is very critical so that you get the results you want.

The difficulty with contact sheets, is that they are great to judge the image composition from, but will be printed so that the image looks good on paper, so corrections are made to compensate for over/under exposure, as well as lighting.
This is why contacts (or any print from a neg) can be misleading, as it all depends on how it was printed, so, if you don't like the results, it's worth asking for another try, especially if it is a machine done, or other low end print service.

The best way to determine correct exposure is to examine the negs, and if you lack the experience, get the lab to give you their opinion.
Typical neg film has a bit of underexposure latitude(less then a stop), and quite a bit (2-3 stops) of overexposure latitude.
C-41 films don't push/pull well, but it's seldom necessary, and not recommended, unless there is a large error in exposure.
If you have processing facilities nearby, try a box and see how it will work for you.

Personally, I intend to give this film a try, as I'm interested in the degree of latitude that it can give.
