Well did you open any bleeder lines that would let air in or did you replace the pads as well as the rotors? Pads that are worn to the profile of old rotors will take time to conform to the shape of the new rotor. Also the spongy feel is most likely break in time. Even if you did replace the pads as well it takes a good long while, like 400 miles in some cases to seat the pads and embed the rotors with the pad material. Just drive it easy with no hard braking for a tank of gas or two and it should improve with time.

The pads whether new or existing need to be bedded in. You really should have put new pads on as well. Also if you had to compress the caliper pistons to get them back on over the new rotor you should also bleed the system. Heck you should bleed the system regardless as this would be an excellent time to do it.
