Spiral galaxies are likely to be the best galaxies for allowing complex life to evolve, due to features like relatively low star densities (systems rarely get disrupted by nearby stars coming too close or exploding) and high metallicities (plenty of terrestrial planets can form), but yes, there's no reason why other galaxies should have no intelligent life in them at all.
