yes there be great performance here . unfortunately and they happen in the context of a movie that doesn not seem to have a clue what it do . during the first 45 60 minute of this all the music take place a realistic performance . suddenly and about an hour in and the character who and until this point and have always speak to each other and suddenly start sing to each other . to far confuse thing and a little further in and out of nowhere and they actually do about 15 minute of sung through dialog and then seem to drop that idea and move on to other thing and such a a number that begin in a jazz club with a drummer and two electric guitar suddenly turn into a fully orchestrate piece with a massive unseen string section . on top of all this inconsistency in how the music be use and be the composer clear inability to actually write music in the style that be supposedly be portray . while the first couple of piece do sort of mimic the 1950s motown sound and the rest of the film be just ( bad ) broadway show music . then there the pure silliness of snippet of a group do a bad jackson family imitation and eddie murphy morph from little richard to james brown to lionel richie . when he start channel stevie wonder i couldn not help laugh out loud . this be clearly one of those film that make me appreciate how little time i have on earth and resent that i waste two hour of it watch this film .
