After reviewing the first film I felt the need to watch back to the future 2 and review it because its a great film. Right after the events of the first film the doc comes back and takes marty and jennifer to the year 2015 to save their child but in doing so help create an alternate 1985 that they have to save. Michael k fox is back as marty mcfly and he is great in this film, just like in the first film he has this boyish charm about him that makes you want to see him succeed and make things right in his life. Christopher Lloyd is back as doc brown and once again he is a great companion for marty on this adventure. He is smart, funny and has great chemistry with fox just like the first film. This is the film where the character of biff becomes the main villain and he was great in this film, really delivering a fun over the top bad guy performance that definitely boosts the film. The returning lorraine and jennifer characters also do a decent job with what they are given in this film. The story has some interesting ideas in it considering dark alternate timelines which I liked but it does feel like this films story is a bit unfocused. There is allot going on and I felt like some of it was unnecessary and just pandering to fans of the original film. But this film has a fantastic ending that sets up a third film perfectly. The script has some fun dialogue in it that does make you smile and also simplify the science. But I do wish they had gone a little further with the drama to really sell this as a darker film. The style is really good with the future very well designed but the film also has allot of fun action scenes to help. This is a great sequel that if you are a fan of the first film you just must see.
