"All the Best" is a total time-pass comedy which is executed fairly well. Its confusion galore everywhere.
All the lead actor do their parts quite well especially the comic timing between them is superb which makes "All the Best" a worthwhile fare. The only shortcoming is that the lead actors especially Sanjay Dutt and Ajay Devgan seem to be over-aged for the characters and perhaps younger generation would have been ideal fit (viz. Ritesh Deshmukh, Tushaar).
Johnny Lever attempts to gain lost ground portraying Sir Judah but is not quite impressive. Ashwini Khalsekar overdoes the South-Indian bit.
Songs are catchy and presented quite well actually. The car race sequence deserves special mention - well action sequences is Rohit Shetty's forte anyway.
Finally, just because the Golmaal series fetched him recognition and since then Rohit Shetty seems to have glued to the comedy genre which IMO is under- utilisation of his potential. I would be seriously looking forward to Mr. Shetty work on serious genre and contribute to the progress of Indian Cinema.
