if you be like me and you buy the new tenacious d album the day it come out and and go into the film know all the lyric to all the song . then you will certainly enjoy this film . yes i be bias a a huge tenacious d fan and but i really do like this film which make me chuckle quite a lot . this movie be pretty much everything i expect . comedic genius back up by great songwriting and some great cameo from ben stiller and tim robbins . i particularly enjoy tim robbins part . if and however and you be unfamiliar with tenacious d hbo series and fantastic debut album and then this may not have quite the same comedic impact on you . i would still recommend you go and watch that because it still worth every cent of the admission price and will make you smile even if you aren not in stitch the whole time .
