Just because you don't have a panty shot every five minutes it doesn't mean Lagrange isn't full of fanservice. Muginami's sole existence is fanservice.
Wait a minute, are we recycling discussions from the anime thread?
I think if it were a "fanservice heavy" show, then every episode would be more like the ones I mentioned. I didn't say it doesn't have fanservice, I just don't consider it particularly heavy by comparison to other shows where it is far more constant and blatant. If there are more episodes like the 1st and 7th then my opinion will obviously change.
