If you're talking about a web app, you should consider that there are ways
around client side validations. If the validation is imperative to the
security or integrity of your app, then you should still check it server
side (and possibly even in the DBMS itself). In these situations, I think it
is fine to "blow up", though. The client side validations are useful to give
a nice interface and ensure valid data with smooth interaction for the user.
The server side are just to maintain integrity/security, if server side
blows up, I don't care about it, it's because of either a bug that should be
fixed, or an insidious user, in which case 500 is probably better than a
polite explanation of the issue that gives them more knowledge.
