(couldn't let this one slip)
Sorry, you're completely incorrect if you consider Enter Shikari to lack musicianship. Not every band in the world has the musicianship of Spastic Ink or Spiral Architect.
The guitarist has a fantastic distortion tone far better than most metal guitarist which is very impressive considering how young the band is, it took Meshuggah 6 years+ to refine their tone to the point of crunchy djent excellence. He also has written some very good riff which are much better than similar bands.
The synths though very typical fit in very well with the mix and definately do add an extra dimension to their music (much more than Jordan Rudess has done for Dream Theater, another band considered to have amazing musicianship unless there are people who exist that actually enjoy his 7 minute long piano concertos)
The actual music itself is very technical, a lot of their songs have complex rhythmic passages and often incorporate time signature changes (similar bands simply don't do this apart from Exit Ten).
The only thing i'll agree with is the singer isn't brilliant but he sounds a lot better than how he used to.
