Probably the only superhero film where I actually slept off for a good 15 minutes. The movie starts very slowly & only when Thor makes an entrance does the pace pick up.
Avengers definitely has its moments - particularly towards the end. The last hour or so is definitely entertaining - especially when you have Hulk going HULK!! SMASH!!?!??!. & Thor flinging his hammer.
Ultimately it's another superhero movie with a ridiculously boring beginning and redeemed by the way it ends.
