That is correct. You need to write the admittance for each series branch and isolate out the real and imaginary parts. For that case the value for the resonate point is 1/root(LC), BUT modified by the root(RL^2-L/C/RC^2-L/C). And hence for the case cited with ideal elements the answer is resonate at all frequencies!
And such are used as "all pass" networks to get phase shifts between two arms.
