Many Novus Ordo churches are ugly and they closely resemble protestant churches. They look like office buildings or plazas. Nothing about the architecture exclaims, "THIS IS THE HOUSE OF THE LORD!"... rather, they are bland, modern - post-modern - contemporary - structures designed for the people, NOT God. These empty structures should be avoided, unless there is no other option but to acquire the building. If possible, traditional Catholics should build their own Chapel or acquire one that has a traditional architecture to it, usually one that was built before VII. I also think Orthodox Church architecture is beautiful.
