Yes, Frozen is a good example of this. Wikipedia is based upon sources. For controversial facts like perceived lesbian undertones, we need to look to the sources to decide the best course of action to describe it effectively or even whether it happened at all. And yes, Frozen 2013 depicts perceived LGBT parallels because that's what sources stated. We stick to the sources. The few I mentioned seem to be leaning in the direction of it describing it as an intense friendship rather than a relationship. Again, needing to wait for more sources.
