Use of CG for some monsters is noticeable but the production values and plot line are high enough it doesn't break it. The Tower of Druaga: Based on a RPG it boasts a strong plot line with good characters. It was only that one time but it scarred me for life 'shudders'. I found the dubbing good until the very end of the first season when Harima 'sings' (and I use the term loosely). The second season also seems to have little more subject matter that makes me uncomfortable while all the first had was poor Harima getting embarrassed through no fault of his own. It's as if the writer only planned the first, had success and then threw together a second.
School Rumble: I liked the first season a lot but the second season seems to lack direction so I've lost interest. I'm not crazy about any of them but I liked them.
