I think it's all a matter of taste. Some movies that I find awful others love and vice-versa. In the same light, some films that critics dub as the most unique/brilliant/moving film of the year are just plain boring.

The ingredients to at least start on should be an original idea, or an original spin on a previous theme. As the "Blank" Movies have proven, this can go horribly wrong. The right actors for the right part, not just casting someone because he/she's popular. Avoid remakes or adaptations unless one is required...if the original is a classic leave well alone. I think these points can be applied to any genre of film as a solid starting point.

As long as you find it interesting and enjoyable, then it's worth it. Of course, most of the new movies out there are not.

I once always love action and thriller when I was young but when I became old and I start love drama, storylines and developed characters now. But I didn't enjoyed watched most films that were made in 2000's and only very rare movies in this decade that I like. Overuse of CGI, poor storylines, lack of feeling, remaking of the classic films, sequels, making films for money, too much teen films and present sociality are ones of reasons.

I enjoy lots of old films from 1960's, 1970's, 1980's and 1990's. I'm current watch Lawrence of Arabia. I can understand why this movie is so great.

Hm...for me, a good movie has to be first of al touching. And to have a damn good story, even if it's a plot that's been used million times before, if it's a good interpretation, that's fine with me. And the most important thing...good actors. Even if you have a brilliant story and technology, actors can ruin everything. Just saw a japanese movie like that...
