Well....let's start with the 3 stars. John Barrymore for all his hamminess,was an actor of his time. ( i.e. "everybody looks hammy",there was no sound to emote a characters feelings in the silent era. ). Even Lon Chaney Sr. was a victim of scenery chewing. So,you have to see beyond that,first and foremost. The fact that this version of "Dr.Jekyll" uses the new process that eliminates all the silent film flaws,such as unscripted black outs,and cartoony movements,is a big bonus. It's a good movie,though a bit long winded,at times,by today's standards.
And now the bad bits,or where the missing 2 stars went:
1) The title cards are not complete originals,they go from decorative,to semi-decorative,to added in at a much later date.
2)The "music" score for this version is an absolute joke. A monkey on a caliope would've scored it better. Half of the music is nowhere near correct for the scenes.( Try to imagine a wind up jewelery box,playing during one of Dr.Jekyll's murderous rages.).I've heard a live organ accompaniment to this film,and this DVD version,isn't it.
3) The "extras" are nothing more than a "feeble" interactive quiz,a picture of a lobby posters,and a "trailer". ( Although I'm not sure they had film trailers in the 1920's.)
If you MUST have this film,the price is right,but by all means turn down the sound and put on your own choice of "scarey music"....or a collection of music boxes if you like it that way.
