If you mean the adopted style for this wikia, then it is correct.
If you mean the standard conventions of publishing, Wikipedia and the like, then it is incorrect. The short version is that the titles of larger works—like feature films, television series, novels and music albums—should be italicized. Parts of larger works—such as scenes, episodes of TV series, chapters and songs—should be placed in double quotes. Also, italics can be very hard to read depending on the resolution, font, font color, background, etc.
Of course, many fan websites treat this as a matter personal preference. But just because it is accepted practice does not make it correct. However, this being a wikia, consensus trumps convention. No matter how much it may annoy me.
