No soundbar is going to replace the 'surround sound' of a 5.1 or 7.1 powered system. The better soundbars will come close but I think you are expecting too much. Most owners wish to increase the sounds from their screens when watching broadcast TV or to enjoy better dialogue. For the 'film effects' you really need to invest some serious money on an amp, decent speakers, cables and associated equipment. Any soundbar even those costing £1500 have their limits from an object maybe at the most 100 cm long and 20 cm high powered by just an HDMI cable and a plug!
