Yes. Things like that, plus the certificate, the mood you're in, the usual reasons for sitting down to some visual presentation. Also, on imdb the scores are incredibly mean average for very popular movies and can vary wildly on the lesser known. If you take a look at a movie you love, and one you hate, you can find a surprisingly short width of score. What this means is that the meaningful scores are 6ish to 8ish. Most popular Movies sit in that area, hence a 6ish in genre you like may actually be rated great by you and an 8ish in genre you dislike might mean you'd appreciate it though not love it.
