A strange bracket problem with large matrix.# TeX - TeX电子排版系统

I have the following code to write a large matrix. But the bracket enclosing
the matrix looks very ugly. Does any one know how to solve this problem?
The code is:
\begin{equation}
\widehat{\mathbf{Z}^2(t)}=\left[\begin{array}{ccccc}
W^+_1& W^-_1& \cdots& W^+_N&W^-_N
\end{array}
\right] \cdot \left[\begin{array}{c} f^+_1(t) \\
f^-_1(t) \\
\cdots \\
the matrix looks very ugly. Does any one know how to solve this problem?
