Is IMAX 3D worth a two hour drive?

It's tough for my husband and I to find sitters, so since we are both big HP fans I planned a sitter way in advance. We have this rare opportunity to have a real date night, so I thought about getting IMAX 3d tickets, but the closest one is in Houston (2 hours from here) and I haven't actually ever been to one...just wanted opinions on whether or not it was worth the drive. Thanks!
