I hope it's really good because so many people want it to be terrible.
So do I
Slightly more seriously it amuses me that people get so worked up over new versions of an old film or new films in a serious based purely on rumours, static images and their perceptions of the cast ("I don't like that one they were in several films I didn't like as they weren't aimed at my preferences").
I suspect if the original Ghostbusters film had been made now there would have been a lot of people making similar comments about how it's going to be terrible, how the uniforms don't look great etc.
I'll tend to try and wait without any expectations of the film and hope for the best, after all it's not like films are the only thing to get new versions with new casts every now and then, the theatre has been doing it since before Shakespeare was born, and the likes of the modern theatres modify the setting/cast gender and cast entirely on a regular basis (IIRC some people were very much against the BBC Sherlock series as it "looked odd" and "out of place" set in modern London).
You can't tell how good a film is going to be until it's been released, I've seen some that looked awesome in the promo shots, the advertising and trailers and had a cast who were all great actors in their own rights, but the film itself has been utterly rubbish* with the only good bits those that were shown in the trailers.
I've also seen films where pretty much everything before it was released suggested it was going to be bad, and it's been excellent.
Same with actors etc, there are actors who I have absolutely hated everything they've been in, then thoroughly enjoyed their work in a new role.
I'm quite aware of the fact that I'm not likely to enjoy an actor doing a role in a rom com aimed at young women, or a role in something like Twighlight, but that doesn't mean I'm not going to enjoy their work in something that is aimed more at my tastes (except Kirsten Stewart, I've had the misfortune of watching her ruin films that if someone else had been playing the role would have been much better).
*I remember much of the excitement before Star Wars Episode 1 was released, and how it turned out.
