With the rise of technology, filmmaking has evidently evolved in the past few decades. Filmmakers are given more options with lighting, sound, advanced cameras and of course, visual effects. The biggest conflict when it comes to visual effects is to choose between Computer Generated Imagery, CGI or practical effects, physically produced visuals. Both have their advantages and disadvantages, and we are ready to discuss it.
With practical there is so much you can do. It is more of a challenge to craft and sometimes it can be a little expensive. Those are the only disadvantages. Practical effects deliver so much to the film. Christopher Nolan uses almost all practical effects for his movies, this is not because he hates CGI but it's for the actors. In an interview, Matthew McConaughey said about 'Interstellar': "The scenes were intimate and personal ... We did not have to play pretend. You see and feel exactly what we saw and felt" The usage of practical effects gets the most out of the actors and that is why many Hollywood directors prefer them, however, there are limitations to their extend.
The wonderful thing about CGI is that filmmakers can create sets and characters that were thought to be impossible. The greatest successes with CGI are Gollum, a skinny and corrupted creature in the 'Lord of the Rings' series, Caesar, an emotional ape in 'Planet of the Apes' and giant fighting robots in 'Pacific Rim'. The repulsion towards CGI is because directors today are relying way too much on it; they aren't taking the challenge of practical but going straight to CGI or we can put it the way Tarantino elegantly did: “This CGI bulls*** is the death knell of cinema. If I’d wanted all that computer game bulls***, I’d have stuck my d*** in a Nintendo.” If CGI is not done well, it really takes away the illusion of the film and takes too much attention to itself, such as the movies 'I am Legend' and 'Scorpion King'.
Overall, I think there is a thin line. I think practical effects should be used as much as they can be and CGI used for impossible parts. They are both good for their own things. So tell us in the comments, which one you prefer, so we can discuss.
