In my opinion, the main downside of goa is the "psychedelicness" attached to it. I wish there could be more breaking free of these norms. New school goa as it is today seems to steer in the opposite direction, with even longer tracks, more subtle melodies and less distinctive arrangements. I would totally dig an album that embraces the melodic, cybernetically atmospheric side of goa trance and avoids samples about drugs or spirituality, emphasizing the personality of each individual track (through distinctive melodic hooks and recognizable sound textures) instead of conformity between tracks. Shorter track lengths, all-business and no foreplay - but still not goofy and stupid (Finland, you hear me?) - and many tracks on an album, with chill out tracks if they make sense as interludes or otherwise, and not "because they have to be there". If so, I'd like a focus on a more cinematic aspect of the ambience, instead of the ethereal, untouchable, transcendental.
Kind of a popularized goa, if you wish. But dismissing it as that would be missing the point, I think.
